Question

If a solid line represents a covalent bond and a dotted line represents intermolecular attraction, which of the choices shows a hydrogen bond? H 4 C ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ H − F H 3 N ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ H − O − H H − H H 2 O ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ H − CH 3

Answer 1

H 3 N ⋅ ⋅ ⋅ ⋅ ⋅ ⋅ H − O − H

Step-by-step explanation:

Answer 2

H-O-H water

Step-by-step explanation:

hydrogen bonds occur when hydrogen atom undergoes dipole-dipole attraction to an electronegative atom such as hydrogen and fluorine, oxygen or nitrogen
