Solution: Which of the following molecules can form hydrogen bonds with other molecules of the same kind?a. CH3Fb. CH3NH2c. H2Od. HIe. CH3-O-CH3f. CHCl3g. HCOOH 

Problem

Which of the following molecules can form hydrogen bonds with other molecules of the same kind?

a. CH3F
b. CH3NH2
c. H2O
d. HI
e. CH3-O-CH3
f. CHCl3
g. HCOOH

 

Solution

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.


a. CH3F

# 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-
