With respect to the compounds I-V, choose the correct statement(s).\[\begin{array}{l}
\text { I }\\
\text { II }\\
\text { H- } \mathrm{CH}_{3}\\
\text { III }\\
\text { IV }\\
\text { V }
\end{array}\]
- The acidity of compound I is due to delocalization in the conjugate base.
- The conjugate base of compound IV is aromatic.
- Compound II becomes more acidic, when it has a – NO2 substituent.
- The acidity of compounds follows the order
I > IV > V > II > III. (2020/Shift-1)
Answer
(A) The acidity of compound I is due to delocalization in the conjugate base., (B) The conjugate base of compound IV is aromatic., (C) Compound II becomes more acidic, when it has a – NO 2 substituent.
