`C Cl_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A, D
`NH_(3)` and `CF_(2)Cl_(2)` (freon -12) are used as refrigerants. That of water `[E^(@)=-0.83V]` . Hence, their ions in the aqueous solution can not be reduced. Instead water will be reduced `2H_(2)O +2e^(-) to H_(2) + 2OH^(-)`
