MCQ
Consider the following compounds :
Hyperconjugation occurs in
- ✓$III$ only
- B$I$ and $III$
- C$I$ only
- D$II$ only.
✓
Answer
Correct option: A.
$III$ only
a
Hyperconjugation occurs through the $H-$ atoms present on the carbon atom next to the double bond i.e alpha hydrogen atoms. There is no alpha $-H$ in the structure $I$ and $II$.
Hyperconjugation occurs through the $H-$ atoms present on the carbon atom next to the double bond i.e alpha hydrogen atoms. There is no alpha $-H$ in the structure $I$ and $II$.
So, hyperconjugation occurs in structure $III$ only ie.
