Question

How to covert ethanol into 2-butanol.(show reaction)​

Answer 1

Explanation:

Conversion -

• Ethanol to 2-butanol

CH₃–CH₂–OH → CH₃–CH₂– CH(OH)–CH₃

Explaination -

CH₃–CH₂–OH + HCl → CH₃–CH₂– Cl + H₂O

Now,

CH₃–CH₂– Cl + 2Na + Cl–CH₂–CH₃ → CH₃–CH₂–CH₂–CH₃ + 2NaCl (wurtz reaction)

Now,

CH₃–CH₂–CH₂–CH₃ + Cl₂ → CH₃–CH₂–CH₂–CH₂–Cl + HCl (Halogenation)

Now,

CH₃–CH₂–CH₂–CH₂–Cl + KOH (alc.) → CH₃–CH₂–CH=CH₂ + KCl + H₂O

Now,

CH₃–CH₂–CH=CH₂ + H₂O → CH₃–CH₂–CH(OH)–CH₃ (Hydration of alkene by MR addition rule)
