Question

Which is formed when diethyl ether is heated with
excess of HI?
(a) Ethyl alcohol and ethyl iodide
(b) Ethyl iodide only
(6) Ethyl alcohol only
(d) Ethyl iodide and ethane​

Answer 1

• D is the answer Iof the question

Answer 2

When diethyl ether is heated with excess of HI is Ethyl iodide only. The reaction is explained below :

- Alcohols are formed when ether is reacted with HI and corresponding haloalkanes are formed on reaction of ether with excess of HI .

- So, when diethyl Ether is heated with hydro iodic acid than ethyl alcohol and ethyl iodide is formed.

CH3CH2OCH2CH3 + HI → CH3CH2-I + CCH3CH2-OH

- And when present in excess the ethyl alcohol formed under reaction with HI is further to give ethyl iodide.

CH3CH2-OH + HI → CH3CH2-I + H2O

- Hence, the overall reaction comes out to be :

CH3CH2OCH2CH3 + 2HI → 2CH3CH2-I + H2O

- So, only ethyl iodide is formed.
