Answer:
Which of these will form hydrogen bonds?
a. CH2Br2
b. CH3OCH2CH3
c. H2NCH2COOH
d. H2SO3
e. CH3CH2OH
Explanation:
A hydrogen bond is the weak electrostatic force of attraction that exists between a covalently bonded hydrogen atom and a highly electronegative atom like N,O, and F.
For example, water has a hydrogen bond between the hydrogen atoms of one molecule and the oxygen atom of another molecule.
Among the given molecules,
a. CH2Br2 does not have a hydrogen bond because it does not have N or O or F.
b. CH3OCH2CH3 does not have a hydrogen bond.
Due to the absence of -OH or -NH or H-F bonds.
c. H2NCH2COOH shows hydrogen bonding.
d. H2SO3 has hydrogen bonding.
Due to the presence of -OH bond.
e. CH3CH2OH has hydrogen bonding.
Due to the presence of -OH bond.
