1.	What is the hybrid state ofBeCl_(2) ? What will be the change in the hybrid state ofBeCl_(2)in the solidstate ?
Answer» <P> Solution :In the vopour stateat hight temperature , `BeCl_(2)`existsas linear molecule , `Cl - Be - Cl`. The hybridization of the central atom sp . In the solid state, it has a polymericwith chlorine bridges as follows : Two Clatoms are linked to Be atom by two coordinate bonds and two by covalent bonds. Forthese bonds to be formed , Be in the excited state with the configuration` 1s^(2)2s^(1) 2 p_(X)^(1) 2p_(y) ^(0) 2p_(Z)^(0)`undergoes ` sp^(3)`hydridisation . Two half-filled HYBRID orbitals will form normal covalent bonds with two Cl atom. The other two Cl atoms are COORDINATED to Be atom by donating ELECTRON pairs into the empty hybrid orbitals
