MCQ
The labelled $-O^{18}$ will be in
- A$H_2O$
- ✓Methyl benzoate
- CBoth $(a)$ and $(b)$
- DBenzoic acid
✓
Answer
Correct option: B.
Methyl benzoate
b
$(b)$ In esterification acid gives $OH^{\ominus}$ whereas alcohol gives $H^+$.
$(b)$ In esterification acid gives $OH^{\ominus}$ whereas alcohol gives $H^+$.
Product of the reaction is methyl benzoate $\begin{array}{*{20}{c}}
