Hybridization and Polarity Quiz

What is the definition of polarity in chemistry?

• The separation of electric charge within a molecule

• The process of converting a solid into a liquid

• The ability of a substance to dissolve in water

• The process of combining two or more substances to form a new substance

Which type of bond is formed due to the overlap of atomic orbitals?

• ionic bond

• hydrogen bond

• covalent bond

• metallic bond

What is the hybridization of carbon in methane (CH4)?

• sp

• dsp3

• sp3

• sp2

What is the shape of a molecule with sp3 hybridization?

• linear

• octahedral

• planar

What is the difference between sigma and pi bonds?

• Sigma bonds are formed by the overlap of atomic orbitals along the axis perpendicular to the bonding atoms, while pi bonds are formed by the overlap of atomic orbitals along the bonding axis.

• Sigma bonds are stronger than pi bonds.

• Sigma bonds are formed by the overlap of atomic orbitals along the axis between the bonding atoms, while pi bonds are formed by the overlap of atomic orbitals above and below the bonding axis.

• Sigma bonds are formed by the overlap of atomic orbitals above and below the bonding axis, while pi bonds are formed by the overlap of atomic orbitals along the bonding axis.
