Question

Aniline dissolves in $HCl$ due to the formation of:

• A. anilinium chloride
• B. o-chloroaniline
• C. azo dye
• D. diazonium chloride

Answer 1

The correct option is A anilinium chloride

Aniline is basic in nature and $HCl$ is an acid. So, acid-base reaction will take place.

In aniline, the lone pair of electrons is partially delocalized into the benzene ring and is thus, available for protonation by an acid.

Hence, aniline dissolves in acid like $HCl$ forming anilinium chloride salt.

Therefore, the answer is option $A$.
