an Organic compound `(A) (C_(4)H_(6))` forms a precipitate with Tollens and Fehling's reagents. `(A)` has an isomer `(B)`. `(B)` reacts with `1 mol` of `Br_(2)` to form `1,4`-dibromo-2-butene. `(A)` and `(B)` are:

A

a.

B

b.

C

c.

D

d.

Text Solution

Verified by Experts

The correct Answer is:
A
`DU` in `(A) =2^(@)`. So it contains terminal triple bond, since Tollens reagent and Fehling's solution, besides aldehydes, also react with terminal triple bond. Triple bond it isomeric with diene. `(B)` must be a diene, since it reacts with `Br_(2)` to give `1, 4-addition` product.

So the answer is `(a)`.
