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 $D$.

List-$I$ (Test)	List-$II$ (Identification)
$A$. Bayer's test	$I$. Phenol
$B$. Ceric ammonium nitrate test	$II$. Aldehyde
$C$. Phthalein dye test	$III$. Alcoholic-$OH$ group
$D$. Schiff's test	$IV$. Unsaturation
