1.	A metal complex Cr(NH_(3))_(4)Cl_(2) having molar conductivity corresponding to 1:1 electrolyte have been isolated in two Forms (X) and (Y), (X) reacts with AgNO_(3) giving white precipitate which turns yellow on reaction with sodium arsenite whereas (Y) gives a yellow precipitate soluble in concentrate NH_(4)OH The hybridization of chromium in complexes (X) and (Y) are :
Answer» both `SP^(3)d^(2)` both `d^(2)sp^(3)` `d^(2)sp^(3)" and "sp^(3)d^(2)` respectively `sp^(3)d^(2)` Solution :`underset(d^(3))(X) to underset(d^(2)sp^(3))[Cr(NH_(3))_(4)ClBr]Cl,(Y) to underset(d^(2)sp^(3),mu=3.8 B.M.)[Cr(NH_(3))_(4)Cl_(2)]Br` `"EAN" to 24-3+12=33` Both X and Y can show G.I.
