1)Define the term'geometric isomers'
2)Give geometric isomers and corresponding names for the following condensed structural formula: CH3CH2(CH)2CH3
Geometric isomers are compounds that have the same atoms connected in the same order but the relative positions of the atoms are different.
CH3CH2(CH=CH)CH3 I presume is what is meant.
There are two geometric isomers, one where the Hs of the CHs are on the same side and one where they are on opposite side of the double bond.
The names are
Z-2-pentene
(see http://www.chemspider.com/Chemical-Structure.4483638.html)
and
E-2-pentene
(see http://www.chemspider.com/Chemical-Structure.4483639.html)
1) Geometric isomers are a type of stereoisomers that have the same molecular formula and connectivity of atoms but differ in the arrangement of atoms or groups around a double bond or a ring. This difference in arrangement leads to different physical and chemical properties.
To determine if a compound has geometric isomers, you would need to identify the presence of a double bond or a ring in the molecule. Then, you would examine the positions of the substituents or atoms around the double bond or within the ring.
2) The given condensed structural formula is CH3CH2(CH)2CH3. Let's identify the potential geometric isomers:
To determine the geometric isomers, we will look for the presence of a double bond or a ring in the molecule. In this case, there is no double bond or a ring present. Therefore, we cannot have geometric isomers for this particular molecule.
Since there are no geometric isomers, there are no corresponding names.
In summary, the condensed structural formula CH3CH2(CH)2CH3 does not have any geometric isomers.
