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.
