Phthalic anhydride

Vedclass · Answer

(B) The starting material is $1,2-bis(hydroxymethyl)benzene$ (also known as $o-xylene$ glycol).$1$. Vigorous oxidation of $1,2-bis(hydroxymethyl)benzene$ using a strong oxidizing agent (like $KMnO_4$) converts the two $-CH_2OH$ groups into $-COOH$ groups,forming $X$,which is Phthalic acid $(benzene-1,2-dicarboxylic \ acid)$.$2$. Upon dry heating,Phthalic acid undergoes dehydration to form $Z$,which is Phthalic anhydride.The reaction sequence is:$1,2-bis(hydroxymethyl)benzene$ $\xrightarrow[	ext{Oxidation}]{} 	ext{Phthalic acid} (X)$ $\xrightarrow[	ext{Heating}]{} 	ext{Phthalic anhydride} (Z) + H_2O$.

Identify $Z$ in the following reaction:
$1,2-bis(hydroxymethyl)benzene$ $\xrightarrow[\text{Vigorous Oxidation}]{} X$ $\xrightarrow[\text{Dry Heating}]{} Z$
