Q. The acidity of the compounds $RCOOH,\ H_{2}CO_{3},\ C_{6}H_{5}OH,\ ROH$ decreases in the order
A) $RCOOH > H_{2}CO_{3} > C_{6}H_{5}OH > ROH$
B) $C_{6}H_{5}OH > RCOOH > H_{2}CO_{3} > ROH$
C) $ROH > C_{6}H_{5}OH > RCOOH > H_{2}CO_{3}$
D) $H_{2}CO_{3} > RCOOH > C_{6}H_{5}OH > ROH$
Explanation
(a)
Carbonic acid is less acidic than carboxylic acids whereas more acidic than phenols and alcohols. Hence, order of acidic strength.
$RCOOH > H_{2}CO_{3} > C_{6}H_{5}OH > ROH$
