The concept of hybridisation has been introduced to explain the shapes of molecules. It involves the intermixing of two or more atomic orbitals belonging to same atom but in or more atomic orbitals beloging to sasme atom but in different sub-shells so as to intermix and redistibute energies to from equivalent orbitals called hybrid orbitals.Depending upon toh enumber and nature of the orbitals involved, the hybridisation may be divided into sp (linear), sp^(2) (trigonal), sp^(3) (tetrahedral), sp^(3)d (trigonal bipyramidal), sp^(3)d^(3) (octahedral) and sp^(3)d^(3) (pentagonal bipyramidal) types. it may be noted that the orbitals of isolated atoms never hybridise and they do so at the time of bond formation. The hybrid state of carbon in C_(2)H_(2) is same as that of carbon in:

Select correct code :- (a) In (BeH_2)_n all bond's are 3c - 2e. (b) In (B_2H_6) , all H-atom are present in a plane (c) In I_2Cl_6 , I-Atom sp^3d^2 hybridised (d) In C_2H_6 , C-atom used vacant orbital in a hybridisation

Number of incorrect statement are- (A) The pi bond between metal and carbonyl carbon reduces the bond order of C-O in carbon monoxide. (B) dz^(2) orbital of central metal atom/ion is used in dsp^(2) hybridisation. (C) CN^(-) is a pi_(-) acid Ligand. (D) All negative ligands are stronger than neutral ligends.
