- Mechanism of reaction.
Since the only product formed is tert-butyl chloride- tert-butyl cation is formed faster than isobutyl cation.
CH3CH=CHCH2CH3 + HBr CH3CHCH2CH2CH3 + CH3CH2CHCH2CH3
? + H-Br CH3CH2CHCH2CH2CH3
2. Since there are 2 possibilities- deciding whether there is any advantage of using 1 over the other
The same reaction with chlorine affords a chloronium ion:
Classified as cyclic terpenes.
