Among the following compounds the one that is most reactive towards electrophilic nitration is
1 Toluene
2 Benzene
3 Benzoic acid
4 Nitrobenzene
Explanation:
Toluene has electron-donating methyl group (while others have electron-withdrawing groups) and hence most reactive towards electrophilic nitration.

Which of the following compounds undergoes nitration more readily?
1 Benzene
2 Benzoic acid
3 Nitrobenzene
4 Toluene
Explanation:
\(\mathrm{CH}_{3}\) group activates the benzene ring, whereas, \(-\mathrm{COOH}\) and \(-\mathrm{NO}_{2}\) deactivates the ring. Hence, toluene \(\left(\mathrm{C}_{6} \mathrm{H}_{5}-\mathrm{CH}_{3}\right)\) undergoes nitration easily.

Some meta-directing substituents in aromatic substitution are given. Which one is strong deactivating?
1 \(-\mathrm{SO}_{3} \mathrm{H}\)
2 \(-\mathrm{COOH}\)
3 \(-\mathrm{NO}_{2}\)
4 \({\text{ - C}} \equiv {\text{N}}\)
Explanation:
\(-\mathrm{NO}_{2}\) group is most deactivating group due to strong \({\text{ - E effect, - I effect and - M effect}}{\text{.}}\)

The set of meta directing functional groups from the following sets is
The groups which direct the incoming group to meta position are called meta directing groups and the effect in known as directive influencing effect.Some examples of meta directing group are \({\mathrm{-\mathrm{NO}_{2},-\mathrm{CN},-\mathrm{CHO}}}\),\({\mathrm{-\mathrm{COR},-\mathrm{COOH},-\mathrm{COOR},-\mathrm{SO}_{3} \mathrm{H}}}\), etc. So, the correct option is (4).
