Question

1. a. label at least two covalent bonds in the diagram above. b. label at least one hydrogen bond in the diagram above. which of the molecules in model 2 would form hydrogen bonds with itself (that is, other mol - ecules of the same type) or with water molecules if in a solution?

Explanation:

Step1: Identify covalent bonds

Covalent bonds are the solid - lines in the molecular structure. In the given diagram, the bonds within the central molecule like the C - N bond and C - O bond are covalent bonds. Mark two such bonds.

Step2: Identify hydrogen bonds

Hydrogen bonds are the dotted - lines in the diagram. They occur between a hydrogen atom bonded to a highly electronegative atom (N, O, F) and another electronegative atom. Mark one such dotted line.

Answer:

a. Covalent bonds: The bond between carbon and nitrogen (C - N) and the bond between carbon and oxygen (C = O) are covalent bonds.
b. Hydrogen bond: The dotted line between the hydrogen of a water molecule and the oxygen of the central molecule is a hydrogen bond.
