In all expected compounds each central atom only uses its s and p-orbitals in hybridization. The relationship between bond angle 'theta' and decimal fraction of s and p character present in the equivalent orbitals is given by : costheta=(S)/(S-1)=(P-1)/(P), S=decimal fraction of s-character in the equivalent hybrid orbitaland P=decimal fraction of p-character in the equivalent hybrid orbital. . Q.The incorrect statement is :

Answer»

The ratio in % p-character to % s-character is less than four, for the bond pair of CENTRAL atom of compound S
Central atom USES three hybrid orbitals to form COMPOUNDS R
Central atom uses four hybrid orbitals to form compounds S
There are three compounds present between point C to E, according to % s-character in bond pair of central atom.
