Question

Identify The Compound(S) Containing Polar Covalent Bonds. Select All That Apply. Select All That Apply: a)F2, b)HBr, c)N2, d)CO2

Answer 1

HBr and CO2 contain polar covalent bonds, while F2 and N2 do not because they are homonuclear diatomic molecules with equal electronegativity sharing.

Step-by-step explanation:

Compounds containing polar covalent bonds are those in which there is a significant difference in electronegativity between the atoms, causing a separation of charges within the molecule. Among the compounds listed (F2, HBr, N2, CO2), the following contain polar covalent bonds:

• HBr: Hydrogen bromide has a polar bond because there is a significant difference in electronegativity between hydrogen and bromine.
• CO2: While the molecules as a whole are nonpolar due to the linear structure and symmetrical distribution of charges, carbon dioxide contains polar covalent bonds between carbon and oxygen atoms.

Homonuclear diatomic molecules like F2 and N2 do not contain polar bonds because the atoms involved have the same electronegativity, hence an equal sharing of electrons.
