Question

Which of the following can exhibit geometric isomerism?

a. CH3CH=CHCH3
b. 
c. CH3CH=CH2
d. more than one response is correct
### Question 22:

**Which of the following can exhibit geometric isomerism?**

a. CH₃CH=CHCH₃

b. CH₃CH=C(CH₃)₂

c. CH₃CH=CH₂

d. more than one response is correct

### Explanation:

- **Geometric Isomerism:** A form of stereoisomerism where isomers have the same structural formula but differ in the spatial arrangement of groups around a double bond or ring system.
- **Requirement for Geometric Isomerism:** The carbon atoms involved in the double bond must each have two different groups attached to them.

**Analysis:**

- **Option a:** CH₃CH=CHCH₃ can exhibit geometric isomerism because the two central carbon atoms have different groups attached.
- **Option b:** CH₃CH=C(CH₃)₂ cannot exhibit geometric isomerism because one of the central carbon atoms does not have two different groups.
- **Option c:** CH₃CH=CH₂ cannot exhibit geometric isomerism because the terminal carbon does not have two different groups.

Given this analysis, the correct answer is **a. CH₃CH=CHCH₃**. Only option a can exhibit geometric isomerism, thus option d, "more than one response is correct," is not true.
