We are being asked to determine which among the given molecules can form hydrogen bonds with other molecules of the same kind.
Hydrogen Bond is the force that exists when H is directly connected to F, O, or N.
Let’s draw the Lewis structure of each molecule and determine if there’s an H directly connected to F, O, or N in the molecule.
# of valence e-:
Group Valence Electrons
C 4A 1 x 4 e- = 4 e-
H 1A 3 x 1 e- = 3 e-
F 7A 1 x 7 e- = 7 e-
Total: 14 valence e-
Which of the following molecules can form hydrogen bonds with other molecules of the same kind?
