Question:
A compound of molecular formula C₇H₁6 shows optical isomerism, compound will be
A compound of molecular formula C₇H₁6 shows optical isomerism, compound will be
Show Hint
Presence of at least one asymmetric (chiral) carbon is necessary for optical activity.
Updated On: Mar 19, 2026
- 2,3-Dimethylpentane
- 2,2-Dimethylbutane
- 3-Methylhexane
- None of the above
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Optical isomerism requires a chiral carbon atom (attached to four different groups).
Step 2:
\beginitemize
• 2,3-Dimethylpentane — has plane of symmetry ⟹ achiral
• 2,2-Dimethylbutane — highly symmetrical ⟹ achiral
• 3-Methylhexane — carbon at position 3 is attached to four different groups ⟹ chiral
\enditemize
Step 3: Hence, only 3-Methylhexane shows optical isomerism.
