Which of the following sequence of reactions (reagents) can be used for the conversion of C6H5CH2CH3 into C6H5CH=CH2?

Assertion: Alkynes are more reactive towards nucleophilic addition reaction as compared to alkenes. Reason: Alkynes contain two pi bonds, while alkenes have only one bond.

Assertion:1-butene on reaction with HBr in the presence of a peroxide produces 1-bromobutane. Reason: It involves the formation of a primary radical.

Assertion: The addition of HBr on 2-butene gives two isomeric products. Reason: Addition of HBr on 2-butene follows Markownikoff’s rule.
