Optical Rotation and Taste, quick, simple and correct.

Optical rotation, taste, and solubility in (S)-3-methylhexane. Just answered the question for a class.

In chemistry, an enantiomer ( /ɨˈnæntɪ.ɵmər/ ə-nan-tee-ə-mər; from the Greek ἐνάντιος, opposite, and μέρος, part or portion) is one of two stereoisomers that are mirror images of each other that are "non-superposable" (not identical), much as one's left and right hands are "the same" but opposite [1] (It can be clearly understood if you try to place your hands one over the other without touching the back or palm of the left to the same of the right. You observe that the thumb of one is always over the little-finger of the other, thus explaining the non-superimposable or non-coincident property known as chirality.)

Organic compounds that contain an asymmetric (chiral) Carbon usually have two non-superimposable structures. These two structures are mirror images of each other and are, thus, commonly called enantiomorphs (enantio = opposite ; morph = form) Hence, optical isomerism (which occurs due to this same mirror-image properties) is now commonly referred to as enantiomerism
Enantiopure compounds refer to samples having, within the limits of detection, molecules of only one chirality.[2]
Enantiomers have, when present in a symmetric environment, identical chemical and physical properties except for their ability to rotate plane-polarized light (+/−) by equal amounts but in opposite directions (although the polarized light can be considered an asymmetric medium). A mixture of equal parts of an optically active isomer and its enantiomer is termed racemic and has zero (± 0) net rotation of plane-polarized light.
Enantiomers of each other often show different chemical reactions with other substances that are also enantiomers. Since many molecules in the body of living beings are enantiomers themselves, there is often a marked difference in the effects of two enantiomers on living beings. In drugs, for example, often only one of a drug's enantiomers is responsible for the desired physiologic effects, while the other enantiomer is less active, inactive, or sometimes even responsible for adverse effects (unwanted side-effects).
Owing to this discovery, drugs composed of only one enantiomer ("entantiopure") can be developed to enhance the pharmacological efficacy and sometimes do away with some side effects. An example of this kind of drug is eszopiclone (Lunesta), which is enantiopure and therefore is given in doses that are exactly 1/2 of the older, racemic mixture called zopiclone. In the case of eszopiclone, the S enantiomer is responsible for all the desired effects, though the other enantiomer seems to be inactive; while an individual must take 2 mg of zopiclone to get the same therapeutic benefit as they would receive from 1 mg of eszopiclone, that appears to be the only difference between the two drugs

The formula for 2-pentanol is C5H12O.

However, when you draw the structure, be sure to make sure that the hydroxide branch is on one of the second carbons, because it is 2-pentanol. For example:
H
|
H O H H H
| | | | |
H - C- C - C- C - C - H
| | | | |
H H H H H

The structure could also very likewise be drawn with the hydroxide group going downwards or on the "4th" carbon (this term is incorrect, because the carbon is second from the right and therefore would be called the second carbon oncemore, but for clarity, I termed it the "4th" carbon).

NOw figure out where you can get the properties

As pentanol has one chiral centre, this style of presentation is best in a text format like this

CH3-C(H)-OH

(where the remainder of the chain is behind the page)

the other isomer is then

HO-C(H)-CH3

(again where the remainder of the chain is behind the page)

make a model to see how this works

a)boiling point

this is bulk property and will be the same for the two isomers

b)optical rotation

(if we are talking about specific rotation) this will be equal but with opposite signs.

c)solubility in hexane

same

d)density

a bulk property so the same

e)solubility in (S)-3-methylhexane

f)dipole moment

Same. (If it was different you could separate them by distillation)

g)taste

there may be a difference as taste buds are chiral.

a) Boiling point: I would expect the boiling points of the two enantiomers of 2-pentanol to be identical. This is because boiling point is primarily determined by the intermolecular forces present in a compound. Enantiomers have the same functional groups and overall molecular formula, so their intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, and van der Waals forces) should be similar. Therefore, they should require similar energy to overcome these forces and reach the boiling point.

b) Optical rotation: I would expect the two enantiomers of 2-pentanol to have different optical rotations. Optical rotation is the property of a compound to rotate the plane of polarized light. Enantiomers are mirror images of each other and have the same physical and chemical properties except for their interaction with plane-polarized light. One enantiomer will rotate the plane of polarized light in a clockwise direction (dextrorotatory, or "+" enantiomer), while the other enantiomer will rotate it in a counterclockwise direction (levorotatory, or "-" enantiomer).

c) Solubility in hexane: I would expect the solubility of the two enantiomers of 2-pentanol in hexane to be identical. Solubility is primarily determined by the interaction between the solute and the solvent molecules. Since hexane is a nonpolar solvent, the solute (2-pentanol) will interact primarily through nonpolar forces (dispersion forces). Enantiomers have the same functional groups and a similar molecular structure, so their interaction with nonpolar solvents should be comparable, resulting in similar solubility.

d) Density: I would expect the densities of the two enantiomers of 2-pentanol to be similar. Density is a physical property that depends on the mass and volume of a substance. Enantiomers have the same molecular formula, so their molar masses are identical. Their molecular structures are mirrored images, but the atomic arrangement and bonding are still the same. Therefore, their volumes should be similar, resulting in similar densities.

e) Solubility in (S)-3-methylhexane: I would expect the solubility of the two enantiomers of 2-pentanol in (S)-3-methylhexane to be different. Enantiomers can have different interactions with chiral solvents due to the difference in their spatial arrangement. The (S)-3-methylhexane is a chiral solvent, meaning it can selectively interact with one enantiomer over the other based on their molecular orientation. Therefore, one enantiomer may exhibit greater solubility in (S)-3-methylhexane compared to the other.

f) Dipole moment: I would expect the dipole moments of the two enantiomers of 2-pentanol to be similar. Dipole moment is a measure of the polarity of a molecule, indicating the separation of positive and negative charges. Enantiomers have the same functional groups and a similar molecular structure, so their dipole moments should be comparable.

g) Taste: I would expect the taste of the two enantiomers of 2-pentanol to be similar. Taste is a subjective sensory perception influenced by the interaction of a compound with specific taste receptors in our mouths. Enantiomers typically have very similar chemical properties, including their interaction with taste receptors, and therefore should have similar tastes.
