Question

How many acidic H-atoms are present in this compound that can react with $\stackrel{\ominus }{R}$ for R-MgX to give alkane

Answer 1

Answer: 6.00

Here 6 H-atoms are acidic enough to react with $\stackrel{\ominus }{R}$ for R-MgX.

Here hydrogen atom of $-S{O}_{3}H,-COOH,-C\equiv CH,-OH$ (phenolic and alcoholic both) and $$\begin{gathered} -\text{CH}-{\text{NO}}_{\text{2}} \\ \text{|} \\ {\text{NO}}_{\text{2}} \end{gathered}$$ are acidic.
