Here's 2019 A Level H2 Chemistry Paper 1 Question 24.

2019 p1 q24 qn

P dissolves readily in cold HCl to form a solution which yields a crystalline solid on evaporation.

This means P contains a basic functional group that neutralises HCl to form a salt solution.

On evaporation the solid salt or ionic compound is obtained.

2019 p1 q24 deduce P is basic

Comparing the options,

Compound A is a ketone which is neutral.

Compound B is an amide which is neutral.

Compound C is phenylamine which is basic.
