Question

Q.1.A) Choose the correct option from the following:
The chemical bond formed by the sharing of an electron pair between two atoms so that
both the atoms get their octet complete is called
a)ionic bond
b) covalent bond
c) hydrogen bond
d) carbon bond​

Answer 1

Answer:

b) Covalent Bond.

Explanation:

Covalent Bonds are formed by the mutual sharing of electron pair between two or more atoms of elements.

Answer 2

Answer:-

Covalent bond is the chemical bond formed by sharing of electrons mutually between two atoms of same or different elements to attain the nearest noble gas configuration.

∴ Covalent bond (Option - B) is the required answer.

_________________________________

Characteristics of a Covalent bond:

• Due to the presence of Vander Waals forces (weak forces of attraction) between molecules, Covalent compounds exist mostly liquid or gas of low boiling point. The compounds which exist in solid state having high molecular masses exist as soft solids.

For example,

P₄ , S₈ are soft solids.

• Covalent solids which have three - dimensional structures are insoluble in all solvents. They are mostly soluble in non polar solvents like Benzene, Carbon Chloride , etc.

• Covalent compounds are Bad conductors of electricity since they do not have free Electrons (simply non charged particles) .
