5 . chemical bonding please answer my question as soon as possible to

As bond length is sum of radii ot two atoms and as we move from left to right in a row, radii decreases so bond length decreases. So order of bond length is Si-O>P−O>S−O>Cl−O.. An...

option D Here all have same 2p-3d backbonding now we will check, who will give lone pairs easily to the central atom. left to right tendency to donate electrons increase as EN decr...
