Question

With reference to the scheme given, which of the given statement(s) about T,U,V and W is/are correct?

• 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 $NaHC{O}_3$.

Answer 1

Answer: (A), (C), (D)

The correct options are
A T is soluble in hot aqueous NaOH
C Molecular formula of W is $C_{10}{H}_{18}{O}_4$
D V gives effervescence on treatment with aqueous $NaHC{O}_3$.

(a) T undergoes an ester hydrolysis in hot aqueous alkali as

(b) $LiAI{H}_4$ reduces ester to alcohol as “U”. No chiral carbon, hence it is optically inactive.

(c) U on treatment with excess of acetic anhydride forms a diester a

(d) U on treatment with $Cr{O}_3|H^{+}$ undergoes oxidation to diacid which gives effervescence with $NaHC{O}_3.$
