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 $NaHCO_{3}$

Answer:

Option A,C,D

Explanation:

(a) T is an ester hydrolysis in hot aqueous alkali

'U" No chiral carbon optically inactive'
(c) U on treatment with an excess of acetic anhydride forms a diester as

(d) U on treatment with CrO3 l H+  undergo oxidation to diacid which gives
effervescence with $NaHCO_{3}$
