Answer to Question #333988 in General Chemistry for Mendy

Question

Which of the statements is correct?

1.Carbon may form a polar or non-polar covalent bond.

2.A carbon-hydrogen bond ethane (CH3CH3) is highly polar.

3.In a carbon atom, the 2s and 2p orbitals are equal in energy.

4.Carbon has two valence electrons.

Answer 1

1.Carbon may form a polar or non-polar covalent bond.

Carbon can form nonpolar covalent (pure covalent) bonds when it bonds to itself, as in graphene and diamond. Carbon forms polar covalent bonds with elements that have a slightly different electronegativity. The carbon-oxygen bond is a polar covalent bond.
