Vedclass · Answer

(D) An ester is a chemical compound derived from an acid (organic or inorganic) in which at least one $-OH$ (hydroxyl) group is replaced by an $-O-alkyl$ (alkoxy) group. The general formula for an ester is $RCOOR'$,where $R$ is a hydrogen atom,an alkyl group,or an aryl group,and $R'$ is an alkyl or aryl group.$1$. Calcium lactate is a salt of lactic acid.$2$. Ammonium acetate is a salt of acetic acid and ammonia.$3$. Sodium acetate is a salt of acetic acid.Since none of the given options are esters,the correct option is $D$.

$A$. Formic acid	$I$. Rancid butter
$B$. Acetic acid	$II$. Vinegar
$C$. Butyric acid	$III$. Red ants

Column-$I$ (Reaction)	Column-$II$ (Name)
$A$. $RCH_2COOH \rightarrow[H_2O]{X_2/P} RCH(X)COOH$	$i$. Decarboxylation
$B$. $RCOONa \rightarrow[NaOH, CaO, \Delta]{\text{soda lime}} RH$	$ii$. Grignard reaction
$C$. $RCOOH + R'OH \leftrightarrow{H^{+}} RCOOR' + H_2O$	$iii$. Hell-Volhard-Zelinsky reaction
$D$. $RMgX + R'CHO \rightarrow{H_3O^{+}} RCH(OH)R'$	$iv$. Esterification
