Hydrogen Bond is the force that exists when H is directly connected to F, O, or N.


A. H2O

# of valence e-:

            Group            Valence Electrons
H         1A                   2 x 1 e- = 2 e-
O         6A                   1 x 6 e- = 6 e-

an H is directly connected to O
can form hydrogen bonds


B. CH3OH

# of valence e-:

            Group            Valence Electrons
C         4A                   1 x 4 e- = 4 e-
H         1A                   4 x 1 e- = 4 e-
O         6A                   1 x 6 e- = 6 e-

an H is directly connected to O
can form hydrogen bonds


C. HF
