Class 12th Chemistry 2018 Set1 Delhi Board Paper Solution
(A), (B) and (C) are three non-cyclic functional isomers of a carbonyl compound with milecular formula C4H8O. Isomers (A) and (C) give positive Tollens' test whereas isomer (B) does not give Tollens' test but give positive Iodoform test. Isomers (A) and (B) on reduction with Zn(Hg)/conc. HCl give the same product (D).
(a) Write the structure of (A), (B), (C) and (D).
(b) Out of A), (B), and (C) isomers, which one is least reactive towards addition of HCN?
Experts are working on it.
