Question

For the reaction, product p will be?

Answer 1

Answer:

Correct option is

D



Reaction takes place by carbene mechanism followed by ring expansion.

Carbene adds to (=) bond of five membered ring and simultaneously changes (−NH2) group in six-membered ring to (−N⊕≡C⊖) (isocyanide group) (carbylamine reaction)
