Question

Match the contents in list I (containing compounds) with those in list II (the type of reactions that they undergo).

Answer 1

$\left(A\right)$ $2,4$-dinitrophenol gives reaction with $Na$ and also with $NaHC{O}_3$.
Due to the presence of two electron withdrawing nitro groups, the acidity of phenol is enhanced.
$\left(B\right)$ Benzene sulphonic acid gives reaction with $Na$ and also with $NaHC{O}_3$.
It gives purple color when soda extract of the compound reacts with $N{a}_2\left[Fe\right(CN{)}_{5}NO]$.
This is as per test for sulphur.
$\left(C\right)$ $4$-nitro benzene sulphonic acid gives reaction with $Na$ and also with $NaHC{O}_3$.
It gives blood red color when soda extract of the compound reacts with $FeC{l}_3$.
$\left(D\right)$ Benzoic acid gives reaction with $Na$. It gives reaction with $NaHC{O}_3$ also.

Hence, the correct match is $A=1,2;B=1,2,4;C=1,2,3$ and $D=1,2$.
