Solution:
QUESTION: 15

Covalent-molecules are usually held in a crystal structure by
Solution:

The atoms in molecular covalent molecules are held together by strong covalent bonds. Although these bonds are strong, there are only weak forces of attraction between molecules. These weak attractive forces are called van der Waal’s forces and can be broken with little energy.

QUESTION: 16

Solution:
QUESTION: 19

Hybridization in (C6H5)3C– (on negative carbon) is:
Solution:
QUESTION: 20

Hybridization of carbon C3O2 and CO2 are:
Solution:
QUESTION: 21

Hybridization on central atom in SOF4 is:
Solution:
QUESTION: 22

Hybridization on central atom in Be2C is:
Solution:
QUESTION: 23

Hybridization in N2 is:
Solution:

Pi bond electrons don’t contribute when we calculate the hybridization. So due to one sigma bond and one lone pair hybridization will be “sp”.

Hence D is correct.

QUESTION: 24

Hybridization on the central atom in H3O+ is:
Solution:
QUESTION: 25

Hybridization in Si in Si4O116– is:
Solution:
QUESTION: 26

In octahedral structure the pair of ‘d’ orbitals invo lved is:
Solution:
QUESTION: 27

Solution:
QUESTION: 28

Hybridization state of boron and oxygen in boric acid is:
Solution:

The state of hybridization of boron and oxygen atom in boric acid (H3​BO3​) is sp2,sp3  respectively.

Boric acid ; has a network structure in which boron is trigonal having sp2 and each oxygen atom is tetrahedral having sp3-hybridization with two lone pair of electrons on oxygen.

QUESTION: 29

Which is correct order of bond angle:
Solution:
QUESTION: 30

Which of These is Pyramidal in Shape? 
Solution:

PCl3 has sp3-hybridised phosphorus, with one lone pair. Therefore, molecule has pyramidal shape like ammonia.
