What happens when:
(i). Methyl chloride is treated with alcoholic KCN.
(ii). Ethyl chloride is treated with alcoholic KOH.
(iii). Chloroform is heated with Ag powder.

A

Methyl substituted chlorosilanes are formed

B

Only `Me_(4)Si` formed

C

Polymerised chains of `(CH_(3))_(3) SiCI` are formed

D

silicons are formed

Text Solution

Verified by Experts

The correct Answer is:
A
Methyl substituted chlorosilanes are formed which on hydrolysis give `Me_(2) Si(OH)_(2)` which polymerise to give silicones.
`2CH_(3) CI + Si underset(570 K)overset("cu. Powder)(to) (CH_(3))_(2) SiCI_(2) + CH_(3) SiCI_(3) + (CH_(3))_(3) SiCI + (CH_(3))_(4) Si`
