(b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).b) P4 is non polar covalent.

The resulting CO-NH bond is called a peptide bond, and the resulting molecule is an amide. The four-atom functional group-C(=O)NH-is called an amide group or (in the context of proteins) a peptide group. Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA. peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).
