The approximate shape of a molecule can ...

The approximate shape of a molecule can often be predicted by using what is called the valence-shell electron-pair repulsion (VSEPR) model. Electrons in bonds and in lone pairs can be thought of a ''charge cloud'' that repel one another nad stay as far apart as possible, thus causing molecules to assume specific shapes.
The repulsive interactions of electron pairs decrease in the order:
Lone pair - Lone pair gt Lone pair - Bond pair gt Bond pair - Bond pair
These repulsive effects result in deviations from idealised shapes and alteration in bond angles in molecules.
Among the following molecules.
(P) `XeO_(3)" (Q)"XeOF_(4)`
(R) `XeO_(2)F_(2)" (S)"XeF_(5)`
Those having different molecular geometry but same number of lone pairs on Xe are :

A

P, Q and R only

B

P, Q and S only

C

Q. R and S only

D

P, Q, R and S

Text Solution

Verified by Experts

The correct Answer is:
D

Which among the following molecules have sp^(3)d hybridization with one lone pair of electron on the central atom? (P) SF_(4) (Q) [PCl_(4)]^(+) (R) XeO_(2)F_(2) (S) ClOF_(3)

Valence shell electron pair repusin theory (VSEPR) can be used to perdict the approximate shape of molecules. Electrons in bonds and in lone pairs can ve thought of as "charge cloud" that repel one another and stay as far apart possible, thus causing molecules to assume specific shapes. The repulsive interacions of electro paris decrease in the order : Lone pair-lone pair gt Lone pair -bond pair gt Bond pair -bond pair. These replusions effect result in deviations from idealized shapes and alternative in bond aegles in molecules. The species which has pyramidal shape is :
