Q.
How many acidic H-atoms are present in this compound that can react with $\overset{\ominus}{R}$ for R-MgX to give alkane
NTA AbhyasNTA Abhyas 2020
Solution:
Here 6 H-atoms are acidic enough to react with $\overset{\ominus}{R}$ for R-MgX.
Here hydrogen atom of $-SO_{3}H,-COOH,-C\equiv CH,-OH$ (phenolic and alcoholic both) and $-\text{CH}-\text{NO}_{\text{2}} \\ \, \, \, \text{|} \\ \, \, \text{NO}_{\text{2}}$ are acidic.
