Choose the comound which can react with `[Ag(NH_(3)))(2)]^(+)` and on treatment with alkaline `KMnO_(4)` gives `(CH_(3))_(3)C-O OH`

Options

A. `CH_(3)CH_(2)CH_(2)C=C-CH_(3)`
B. `(CH_(3))_(2)CHCH_(2)C-=CH`
C. `(CH_(3))_(3)C-C-=CH`
D. `(CH_(3))_(3)C-C-=C-CH_(3)`

Answer

C

Explanation

Because the compound reacts with `[Ag(NH_(3))_(2)]^(+)` it must have=CH group. Further as it gives `(CH_(3))_(3)C-COOH` with alkaline `KMnO_(4)` it should have `(CH_(3))_(3)C-C`= group. Therefore the compound is as shown in (C ) `(CH_(3))_(3)C--=CH overset(Alk.KMnO_(4))to (CH_(3))_(3)C-COOH+CO_(2)+H_(2)O`
