A metal complex having composition `Cr(NH_(3))_(4)CI_(2)` Br has been isolated in two forms `A` and `B` The `A` reacts with `AgNO_(3)` to give a white precipitate readily soluble in dilute queous ammonia, whereas `B` gives a pale-yellow precipitate soluble in concentrated ammonia Write the formula of `A` and `B` and state the hybridisation of chromium in each. Calculate their magnetic moment (spin only value) .
