Concepts and reason

The shapes of molecules or ions can be explained based on valence shell electron pair repulsion (VSEPR) model. This model is mainly applicable to p-block elements.

Fundamentals

The main postulates of VSEPR model is as follows:

(i) The shape of molecule depends on the electron-electron repulsions present in the valence shell of the central atom.

(ii) The repulsive interactions between the electron pairs are in the following order:

${\rm{lone pair - lone pair}} > {\rm{lone pair - bonding pair}} > {\rm{bonding pair - bonding pair}}$

(iii) If the central atom forms multiple bonds, then the order of electron–electron repulsions between them is as follows:

${\rm{triple bond - single bond}} > {\rm{double bond - single bond}} > {\rm{single bond - single bond}}$

(a)

The given model is as follows:

The shape of the model is octahedral.

For this shape, the total number of electron groups is 6. The numbering bonding groups is 6 and the number of lone pairs is 0.

Therefore, the answer for (a) is 6,6,0.

(b)

The given model is as follows:

The shape of the model is square planar.

For this shape, the total number of electron groups is 6. The numbering bonding groups is 4 and the number of lone pairs is 2.

Therefore, the answer for (b) is 6,4,2.

(c)

The given model is as follows:

The shape of the model is seesaw.

For this shape, the total number of electron groups is 5. The numbering bonding groups is 4 and the number of lone pairs is 1.

Therefore, the answer for (c) is 5,4,1.

Ans: Part a

The answer for (a) is 6,6,0.

Part b

The answer for (b) is 6,4,2.

Part c

The answer for (c) is 5,4,1.
