In the given esterification reaction,the labelled $^{18}O$ will be found in:

Cyclohexanol and phenol can be distinguished by

Identify the reagents $X$,$Y$,and $Z$ in the following reaction schemes:
$(i)$ Benzene $\xrightarrow{X}$ Benzenesulfonic acid $\xrightarrow{Y}$ Sodium phenoxide $\xrightarrow{Z}$ Phenol
$(ii)$ Aniline $\xrightarrow{X}$ Benzenediazonium chloride $\xrightarrow{Y}$ Phenol
$(iii)$ Chlorobenzene $\xrightarrow{X}$ Sodium phenoxide $\xrightarrow{Y}$ Phenol

The correct match about the reaction sequence shown above is:

From the following,identify the reactions that give alcohol as the product.
