D is N-methyl aniline in the given below sequence of reaction. 
\(\text A\xrightarrow{\bf\text{ reduction }}\text B\xrightarrow{\bf\text {CHCl}_3\text{/KOH}}\text C\xrightarrow{\bf\text{ reduction }}\text D\)

structure of A can be:

1.		2.
3.	CH3NH2	4.

The products formed when Aniline reacts with $B{r}_2$ water, and $NaN{O}_2/HCl$ will be, respectively:

Electrolytic reduction of nitrobenzene in weakly acidic medium gives:

1. Aniline

2. p-Hydroxy aniline

3. N-Phenyl hydroxyl amine

4. Nitroso benzene

Aniline in a set of reactions yielded a product D

The structure of the product D would be:

1. ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2\mathrm{OH}$

2. ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_2{\mathrm{NH}}_2$

3. ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{NHOH}$

4. ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{NHCH}}_2{\mathrm{CH}}_3$

Aniline when diazotized in cold and then treated with dimethyl aniline gives a coloured product. Its structure would be:

1.
2.
3.
4.

Which chemical reaction leads to the formation of isocyanide?

1. Reimer Tiemann reaction.
2. Carbylamine reaction.
3. Hoffmann bromamide reaction.
4. None of the above.

The final product C, obtained in this reaction, would be:
