Problem 11 : Identify the type of reaction (substitution, elimination, addition, or rearrangement) in each of the following reactions:

(a) CH₃CH₂Br + KOH → CH₃CH₂OH + KBr (b) CH₃CHO → CH₃CH₂OH (c) CH₃CH₂OH + H₂SO₄ → CH₃CH₂OSO₃H (d) CH₃CH₂Cl + NH₃ → CH₃CH₂NH₂ + HCl

Solution :

(a) CH₃CH₂Br + KOH → CH₃CH₂OH + KBr: Substitution reaction (b) CH₃CHO → CH₃CH₂OH: Reduction reaction (c) CH₃CH₂OH + H₂SO₄ → CH₃CH₂OSO₂OH: Rearrangement reaction (d) CH₃CH₂Cl + NH₃ → CH₃CH₂NH₂ + HCl: Substitution reaction
