An alkene `(C_4H_8)` reacts with HBr in the presence or in absence of peroxide to give the same compound. Identify the alkene.

Text Solution

Verified by Experts

As the given alkene (molecular formula: `C_4H_8`) reacts with HBr to give the same product in presence and absence of peroxide, the alkene is a symmetrical alkene.
So, a symmetrical alkene with molecular formula `C_4H_8` is but-2-ene `(CH_3CH=CHCH_3)`.
