Question

For each compound in the table below, decide whether there would be any hydrogen-bonding force between molecules of the compound, or between molec of the compound and molecules of water hydrogen-bonding force compound Between molecules of the compound and molecules of water? Between molecules of the formula or Lewis name structure compound? Oves yes сн,о formaldehyde no no н н yes yes Н-с-с-н ethane no no H н н yes yes methanimine H-C N-H no noi Explanation Check O C

Answer 1

To form hydrogen bond with water, there must be N, O or F that will bond with H in H2O

To form hydrogen bond with itself, there must be hydrogen attached to N, O or F atoms.

1)

This has O but both hydrogen are attached to H

So, it can’t form hydrogen bond with itself

It can form hydrogen bond with water

Answer: no, yes

2)

It has neither of N, O nor F

Answer: no, no

3)

It has H attached to N.

So, it can form hydrogen bond with itself

It can form hydrogen bond with water

Answer: yes, yes
