Text Solution

Verified by Experts

a)Add bromise water .Saturated hydrocarbons do not react whereas unsaturated hydrocarbon will decolourise bromise water.
i) `CO_(2)` and `H_(2)O` are formed.
`C_(2)H_(5)OH(l)+3O_(2)(g)to2CO_(2)(g)+3H_(2)O(l)+Heat+light`
ii)Heat energy and light energy.
c)It is because Cl atom substitutes .H. atom of methane to from chloromthane and hydrogen chloride.
