Which solvent would dissolve each of the following compounds?(water, a polar organic solvent, or a nonpolar organic solvent)

a) NaI
b) H3CCH2CH2OH
C)H3CCH2CH2CH2CH2CH2CH2CH3

a. Water

b. a polar organic solvent
c. a non-polar organic solvent.

b is soluble in water, also.

polar

To determine which solvent would dissolve each of the given compounds, we need to consider the polarity of the compounds and the polarity of the solvents. Polarity refers to the distribution of electrons in a molecule, which can affect its ability to dissolve in certain solvents.

a) NaI: NaI is an ionic compound composed of sodium cations (Na+) and iodide anions (I-). Ionic compounds, such as NaI, typically dissolve in polar solvents due to their charged nature. Water is a polar solvent, so it would effectively dissolve NaI.

b) H3CCH2CH2OH: H3CCH2CH2OH, also known as 1-propanol or n-propanol, is a polar organic compound. Polar organic compounds generally dissolve well in polar solvents. Water is a polar solvent, so it would dissolve 1-propanol.

c) H3CCH2CH2CH2CH2CH2CH2CH3: H3CCH2CH2CH2CH2CH2CH2CH3 is an example of an alkane, specifically octane, which is a nonpolar organic compound. Nonpolar compounds typically dissolve best in nonpolar solvents. Nonpolar organic solvents, such as hexane or cyclohexane, would dissolve octane effectively.

In summary:
a) NaI - Water (polar solvent)
b) H3CCH2CH2OH - Water (polar solvent)
c) H3CCH2CH2CH2CH2CH2CH2CH3 - Nonpolar organic solvent (e.g., hexane or cyclohexane)
