The chlorine atom of the following compound that reacts most readily with AgNO 3 to give a precipitate is

Step-by-step solution

The reaction between haloalkane and AgNO gives carbocation intermediate. So, more easily it will be formed, more readily it will react to give precipitate. In the given compound Cl a is easily lost from this compound and carbocation formation takes place readily. This is because this Cl a is closest to electronegative atom 0 , which will attract the electron density towards itself and readily leaves C - Cl a bond. Hence, it will most readily react with AgNO 3 to give precipitate.
