Carboxylic Acids and their Derivatives - Result Question 30
####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 $NaOH$
(b) $U$ is optically active
(c) Molecular formula of $W$ is $C _{10} H _{18} O _4$
(d) $V$ gives effervescence on treatment with aqueous $NaHCO _3$
Show Answer
Answer:
Correct Answer: 16. (c)
Solution:
- (a) $T$ undergoes an ester hydrolysis in hot aqueous alkali as
(b) $LiAlH _4$ 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 $CrO _3 \mid H^{+}$undergo oxidation to diacid which gives effervescence with $NaHCO _3$.
