Amines behave as

The reduction of benzenediazonium chloride to phenylhydrazine can be accomplished by:

Assertion : Aniline does not undergo Friedel-Crafts reaction.
Reason : $-NH_2$ group of aniline reacts with $AlCl_3$ (Lewis acid) to give acid-base reaction.

Which one of the following reactions does not occur?

$(A)$ $\xrightarrow[(1) \text{ excess } CH_3I/K_2CO_3, (2) \text{ } Ag_2O/H_2O, (3) \text{ } \Delta]{} (B)$ $\xrightarrow[(i) \text{ excess } CH_3I/K_2CO_3, (ii) \text{ } Ag_2O, (iii) \text{ } \Delta]{} H_2C=CH-CH(CH_3)-CH=CH_2$. Identify $(A)$.

Assertion: Only a small amount of $HCl$ is required in the reduction of nitro compounds with iron scrap.
Reason: $FeCl_2$ formed gets hydrolysed to release $HCl$ during the reaction.
