Consider the following compounds
Consider the following compounds
hyperconjugation occurs in
A.
I only
B.
II only
C.
III only
D.
I and III
Answer :
III only
Solution :
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 structures I and II.
So, hyperconjugation occurs in structure III only i.e.
