Question

1. in chemistry you learned that covalent bonds are one type of intramolecular bond. they occur between non - metal atoms in a molecule. you may have also learned about a type of intermolecular bond called a hydrogen bond. hydrogen bonds are weak attractive forces between polar molecules containing strong polar bonds such as h - o, h - n or h - f. 19. which of the molecules in model 2 would form hydrogen bonds with itself (that is, other molecules of the same type) or with water molecules if in a solution? a. label at least two covalent bonds in the diagram above. b. label at least one hydrogen bond in the diagram above.

Explanation:

Step1: Identify covalent bonds

Covalent bonds are the bonds where atoms share electrons. In the given diagram, the bonds within the molecules such as the N - H bonds in the nitrogen - containing molecule and the O - H bonds in water molecules are covalent bonds. For example, the N - H bonds in the amino - like molecule are covalent as nitrogen and hydrogen share electrons.

Step2: Identify hydrogen bonds

Hydrogen bonds are weak attractive forces between a hydrogen atom covalently bonded to a highly electronegative atom (O, N, or F) and another electronegative atom. In the diagram, the dotted lines represent hydrogen bonds. For instance, the hydrogen bond between the hydrogen of a water molecule and the oxygen of another molecule is a hydrogen bond.

Answer:

a. Covalent bonds: N - H bonds within the nitrogen - containing molecule, O - H bonds within water molecules.
b. Hydrogen bonds: The dotted lines connecting a hydrogen atom (from H - O or H - N) to an electronegative atom (O or N) in another[LLM SSE On Failure]
