In comparison to $$C-Cl$$ bond in ethyl chloride, the $$C-Cl$$ bond in vinyl chloride is:

$$A + Na/\Delta  \rightarrow$$ no gaseous product
$$A + Br_2/FeBr_3  \rightarrow C_7H_7OBr$$ (two isomers).
Based on the above reactions, identify A from the given options.

 Which of the following is fast debrominated?

Action of alcoholic $$AgNO_3$$ on chlorobenzene is similar to the action on:

An aromatic compound $$\displaystyle 'A' (C_{7}H_{6}Cl_{2}$$), gives $$AgCl$$ on boiling with alcoholic $$AgNO_3$$ solution, and yields $$\displaystyle C_{7}H_{7}OCl$$ on treatment with sodium hydroxide. 'A' on oxidation gives a mono chlorobenzoic acid which affords only one mononitro derivative. The compound A is :
