Question

Covalent-molecules Are Usually Held In A Crystal Structure By?

• A. Hydrogen Bond
• B. Van-der Waals Attraction
• C. Electrostatic Attraction
• D. Dipole-dipole Attraction

Answer 1

The correct option is B

Van-der Waals Attraction

Explanation for the correct option:

Option(B):Van-der Waals Attraction

• The covalent bond is known as the type of bond which gets form by equal sharing of electrons and the shared electrons are called ‘bonding pairs of electrons.
• Although these bonds are strong due to strong interatomic force of attraction, but the forces of attraction existing between molecules are only weak .
• These weak attractive forces are known as van der Waal’s forces which makes the covalent bonds weaker bonds that can be broken with little energy.

Explanation for the incorrect option:

Option(A):Hydrogen Bond

• Covalent-molecules are not usually held in a crystal structure by,Hydrogen Bond.
• Hence, the given option is incorrect one.

Option(C):Electrostatic Attraction

• Electrostatic Attraction does not held the Covalent-molecules in the crystal structure.
• Thus the given option does not coincide with the correct concept.

Option(D):Dipole-dipole Attraction

• Covalent-molecules are not usually held in a crystal structure by,Dipole-dipole Attraction.
• Thus the given option does not represent the correct concept.

Hence,Covalent-molecules are usually held in a crystal structure by,Van-der Waals Attraction.
