The compound X(C5H8) reacts with ammoniacal AgNO3 to give a white precipitate and reacts with excess of KMnO4 to give the acid, (CH3)2CH-COOH. Therefore, X is
CH2 = CH - CH = CH- CH3
CH3(CH2)2C ≡ CH
(CH3)2CH.C ≡ CH
(CH3)2C = C = CH2
C.
(CH3)2CH.C ≡ CH
Since, the compound X gives white precipitate with ammoniacal AgNO3 , it must be terminal alkyne. Moreover, it gives (CH3)2CH-COOH on oxidation with KMnO4 , its structure must be (CH3)2CHC ≡ CH.
The reaction are as follows:
(CH3)2CHC ≡ CH (CH3)2CHCOOH + CO2
(CH3)2CHC ≡ CH (CH3)2CHC ≡ CAg ↓
