Chemical Bonding:Chemical Formulas

Question 1

If Electronegativity difference is > 1.7 What kind of bonding is created?

Answer 1

Ionic bonding

Question 2

If the electronegativity difference is ≤ 1.7 What kind of bonding is it

Answer 2

Covalent bonding

Question 3

If the Electronegativity difference is >0.4 and <1.7 What type of covalent bond is it ?

Answer 3

Polar covalent

Question 4

If the electronegativity difference is ≤ 0.4 What type of covalent bond is this ?

Answer 4

Non-polar

Question 5

What is Intramolecular bonding

Answer 5

Intramolecular bonding is bonding that takes place within a molecule, i.e. it holds the atoms together. Covalent bonding and Polar covalent bonding are examples of intermolecular bonding.

Question 6

What are intermolecular forces

Answer 6

Intermolecular forces are the forces of attraction that exist between molecules. Van der Waal‘s forces, dipole-dipole forces and hydrogen bonding are examples of intermolecular forces.

Question 7

What are Van der Waal’s forces?

Answer 7

Van der Waal’s forces are weak attractive forces between molecules resulting from the formation of temporary dipoles. They are the only forces of attraction between nonpolar molecules.

Question 8

What is intramolecular bonding?

Answer 8

Question 9

What are dipole-dipole forces?

Answer 9

Dipole-dipole forces are forces of attraction between the negative pole of one polar molecule and a positive pole of another polar molecule.

Question 10

What are hydrogen bonds?

Answer 10

Hydrogen bonds are particular types of dipole-dipole attractions between molecules in which hydrogen atoms are bonded to nitrogen, oxygen or fluorine.

The hydrogen atom carries a partial positive charge and is attracted to the electronegative atom in another molecule.

Thus, the hydrogen bond acts as a bridge between two electronegative atoms in separate molecules.
