Identify the functional group that has electron donating inductive effect
1 \(-\mathrm{COOH}\)
2 \(-\mathrm{CN}\)
3 \(-\mathrm{CH}_{3}\)
4 \(-\mathrm{NO}_{2}\)
Explanation:
The functional group that has electron donating or positive inductive effect is \(-\mathrm{CH}_{3}\). Since, the positive inductive effect is due to the presence of an electron donating groups within the polar bond. Thus, option (3) is correct as rest of the three groups \((-\mathrm{COOH},-\mathrm{CN}\), \(\left.-\mathrm{NO}_{2}\right)\) are electron withdrawing in nature.

Among the following, the one that has least \({\rm{p}}{{\rm{K}}_{\rm{a}}}\) value is
1 \(\mathrm{CCl}_{3} \mathrm{COOH}\)
2 \(\mathrm{CH}_{2} \mathrm{ClCOOH}\)
3 \(\mathrm{CF}_{3} \mathrm{COOH}\)
4 \(\mathrm{CH}_{3} \mathrm{COOH}\)
Explanation:
\(\mathrm{CF}_{3} \mathrm{COOH}\) is the strongest acid due to greatest \(-\mathrm{I}\) effect of \(-\mathrm{F}\) atom among \(-\mathrm{Cl}\) and \(-\mathrm{CH}_{3}\).
