Question

State the hybridization of the atom in boldface red type in each of the following molecules and ions:

(a) SF6;
(b) CIO3⁻;
(c) NO3⁻;
(d) OCCl₂

Answer 1

The hybridization of the atoms in the given molecules and ions are as follows: SF6 (sp3d2), ClO3- (sp2), NO3- (sp2), OCCl2 (sp).

Step-by-step explanation:

The hybridization of the atom in each of the given molecules and ions is as follows:

(a) SF6: The central S atom in SF6 makes six covalent bonds with the surrounding F atoms, resulting in an expanded valence shell. The hybridization of the S atom is sp3d2.

(b) ClO3-: The central Cl atom in ClO3- is bonded to three O atoms. It forms three sigma bonds and one pi bond. The hybridization of the Cl atom is sp2.

(c) NO3-: The central N atom in NO3- is bonded to three O atoms. It forms three sigma bonds and one pi bond. The hybridization of the N atom is sp2.

(d) OCCl2: The central C atom in OCCl2 is bonded to two Cl atoms. It forms two sigma bonds and two lone pairs. The hybridization of the C atom is sp.
