Explain why :
Lone pair-lone pair repulsion is more than the bond pair-bond pair repulsion?

Assertion :- The observed bond angle in NH_3 molecule is less than 109^@ 28 '. Reason :-In ammonia molecule, the bond pair-bond pair repulsion is more than the lone pair-bond pair repulsion

Assertion : All F - S - F angle in SF_(4) are greater than 90^(@) but less than 180^(@) . Reason :The lone pair -bond pair repulsion is weaker than bond pair -bond pair repulsion

Valence shell electron pair repulsion theory (VSEPR) can be used to predict the approximate shape of molecules. Electrons in bonds and in lone pairs can be thought of as "charge cloud" that repel one another stay as far apart possible, thus causing molecules to assume specific shapes. The repulsive interactions of electro pair is decrease in the order : Lone pair-lone pair gt Lone pair -bond pair gt Bond pair -bond pair. These repulsions effect result in deviations from idealized shapes and alteration in bond angles in molecules Which of the following is linear ?

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 angles in molecules. The species which has pyramidal shape is :

In a bonded molecule, the order of repulsion between the bonded and non-bonded electrons is (A)lone pair - lone pair > bond pair - bond pair > lone pair - bond pair (B)bond pair - bond pair > lone pair - lone pair > lone pair - bond pair (C)lone pair - lone pair > lone pair - bond pair > bond pair - bond pair (D)bond pair - bond pair > lone pair - bond pair > lone pair - lone p

The space model which is obtained by joining the points representing various bonded atoms gives the shape of the molecule. The geometry of the molecule is definite relative arrangement of the bonded atoms in a molecule. The shape and geometry of a molecule is explained by valence shell electron pair repulsion theory given by Gillespie and Nyholm. Select the correct code for the following repulsion orders, according to VSEPR theory : (I) lone pair -lone pair gt lone pair-bond pair (II) lone pair-bond pair gt bond pair -bond pair (III) lone pair -lone pair gt bond pair-bond pair (IV) lone pair - bond pair gt lone pair-lone pair
