Answer 2

Benzene reacts with propylene in presence of lewis acid BF3 amd forms secondary carbocations

Explanation:

• This reaction is a Friedel crafts reaction.

• It takes place in several steps where at first the alkyl halide$R-Cl$ reacts with lewis acid aluminum chloride$AlCl3$ of boron trifluoride $BF3$
• This reaction is an electrophillic substitution reaction.

• The presence of $BF3$ increases the electrophillicity of alkyl halides.

• In this reaction the formation of primary carbocation which further leads to the formation of the secondary carbocation is formed.
