Compound [A] `C_(4)H_(10)O` is found to be soluble in sulphuric acid. [A] does not react with sodium or potassium permanganate. On heating with excess of HI, it is converted into a single alkyl halide. What is compound [A]

Options

A. Diethyl ether
B. Acetone
C. Butanol
D. Butanal

Answer

A

Explanation

(i) As compound a does not react with sodium metal or potassium permanganate, it cannot be alcohol
(ii) As compound A dissolves in cons. `H_(2) SO_(4)`it may be an ether
(iii) As compound A on heating with an excess of HI gives a single alkyl halide, therefore, compound A must be a symmetrical ether
(iv) The only symmetrical ether having molecular formula `C_(4) H_(10) O` is diethyl ether, Thus compound .a. i diethyl ether ,
`CH_(3) - CH_(2) - O - CH_(2) - CH_(3)`
