हिन्दीIdentify A and predict the type of reaction.\n(Reaction: Chloro/bromo anisole with \( \text{NaNH}_2 \) yielding substitution product)
Correct answer · Option 1
\( \text{OCH}_3 \) group with \( \text{NH}_2 \) attached and elimination addition reaction
Explanation
Reaction of aryl halides with \( \text{NaNH}_2 \) proceeds via a benzyne intermediate, which involves elimination followed by addition (cine substitution can also occur, but benzyne mechanism is elimination-addition). Wait, let's look closely at standard NEET answer key: Elimination-addition (Benzyne mechanism).
