(a) CH3CH2Br + HS– ➝ CH3CH2SH + Br–
This reaction is called nucleophilic substitution reaction.
(b) (CH3 )2 C = CH2 + HCl ➝ (CH3)2C(Cl)CH3
This reaction is called electrophilic addition reaction.
(c) CH3CH2Br + HO– ➝ CH2 = CH2 + H2O + Br–
This reaction is called elimination reaction.
(d) (CH3)3C—CH2OH + HBr ➝ (CH3 )3 C—CH2 Br + H2O
This reaction is called nucleophilic substitution reaction.
