Carboxylic Acids and their Derivatives 2 Question 16
16. With reference to the scheme given, which of the given statement(s) about $T, U, V$ and $W$ is/are correct?
(2012)
(a) $T$ is soluble in hot aqueous $\mathrm{NaOH}$
(b) $U$ is optically active
(c) Molecular formula of $W$ is $\mathrm{C}{10} \mathrm{H}{18} \mathrm{O}_{4}$
(d) $V$ gives effervescence on treatment with aqueous $\mathrm{NaHCO}_{3}$
Show Answer
Answer:
Correct Answer: 16. (c)
Solution:
- (a) $T$ undergoes an ester hydrolysis in hot aqueous alkali as
(b) $\mathrm{LiAlH}_{4}$ reduces ester to alcohol as " $U$ " No chiral carbon optically inactive.
(c) $U$ on treatment with excess of acetic anhydride forms a diester as
(d) $U$ on treatment with $\mathrm{CrO}{3} \mid \mathrm{H}^{+}$undergo oxidation to diacid which gives effervescence with $\mathrm{NaHCO}{3}$.
