Explanation / Answer

1) a) Electrophilic addition

Explanation: Addition of Br2, H2O to alkene produces halohydrin as product.

2) e) Electrophilic aromatic substitution

Explanation: Alcohol on protonation with H2SO4 produces a good leaving group which on further dehydration produces carbocation as an intermediate. Now, the electron density on benzene ring attacks the carbocation and produces substituted product.
