`(KOOC-CH=CH-COOK)` undergoes Kolbe's reaction to form a product which reacts with ammoniacal `AgNO_3` solution to form a precipitate.
The product is a saturated hydrocarbon that forms salt with `AgNO_3`.

Options

A. If both `(A)` are `( R)` are true and `( R)` is the correct explanation of `(A)`.
B. If both `(A)` and `( R)` are true but `( R)` is not the correct explanation of `(A)`.
C. If `(A)` is true but `( R)` is false.
D. If `(A)` is false but `( R)` is true.

Answer

C

Explanation

The product is `CH -= CH` which reacts with Tollens reagent to give `(Ag - C -= C - Ag)` (while ppt.).
So `(A)` is true, but `( R)` is false.
