Treatment of compound \[\begin{array}{cc}
\phantom{.....}\ce{O}\\
\phantom{.....}||\\
\ce{Ph - O - C - Ph}
\end{array}\] with \[\ce{NaOH}\] solution yields
(i) Phenol
(ii) Sodium phenoxide
(iii) Sodium benzoate
(iv) Benzophenone
उत्तर
(ii) Sodium phenoxide
(iii) Sodium benzoate
Explanation:
The carbonyl group is replaced by a methyl group. Clemmensen Reduction is used for this conversion. It's utilised to make cyclohexanone and benzophenone into cyclohexane and diphenyl methane, respectively. The respect is a zinc-hydrochloric acid amalgam.
