Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 1
Save

According to VSEPR theory

Detailed Solution for Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 1

The pairs of electrons tend to occupy such positions that place them farthest from each other and minimise repulsions.

Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 2
Save

In a bonded molecule, the order of repulsion between the bonded and non-bonded electrons is

Detailed Solution for Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 2

Lone pair-lone pair lp - lp repulsions are considered stronger than lone pair-bonding pair lp - bp repulsions, which in turn are considered stronger than bonding pairbonding pair bp - bp repulsions, This is because the lone pair of electrons are attracted towards single nuclei only whereas bond pair electrons are attracted towards two nuclei. Thus the strength of the lone pair-lone pair repulsion is supposed to be more than bond pair-bond pair or bond pair-lone pair repulsion.

Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 3
Save

The shape of water molecule which should be tetrahedral has a bent or distorted tetrahedral shape with a bond angle 104.5°. What could be the reason for this?

Detailed Solution for Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 3

Due to presence of lone pairs, the repulsion is more which changes the bond angle to 104.5°.

Which of the following shapes of SF4 is more stable and why?
Detailed Solution for Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 4

In structure (ii), Ip-bp repulsions are minimum.

Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 5
Save

The most stable shape of ClF3 is shown by
Detailed Solution for Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 5

In (i), the Ip are atequatorial position so there are less Ip - bp repulsions as compared to other positions.

Hence, T-shape is moststable.

The BCI3 is a planar molecule whereas NCI3 is pyramidal, because
Detailed Solution for Test: The Valence Shell Electron Pair Repulsion Theory (NCERT) - Question 14

No lone pair ofelectrons is available in BCI3

One lone pair of electrons is available on N atom, occupies a corner in the tetrahedral arrangement. Therefore, NCI3 appears pyramidal in shape.
