Answer :

Answer: Option (A) is the correct answer.

Explanation:

Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.

Also, more is the mass of a substance more will be its resistance to move from one place to another.

  • Mass of hexane is 86.18 g/mol
  • Mass of [tex]CH_3OCH_2CH_3[/tex] is 60.09 g/mol
  • Mass of [tex]CH_3CH_2OCH_2CH_3[/tex] is 74.12 g/mol
  • Mass of [tex]CH_3CH_2OH[/tex] is 40.06 g/mol

Mass of [tex]HOCH_2CH_2OH[/tex] is 62.07 g/mol

Therefore, out of the given options viscosity of hexane is the greatest.

Answer:

E. [tex]HOCH_2CH_2OH[/tex]

Explanation:

Hello,

In this case, the tendency to form hydrogen bonds (bridges) provides a substance more viscous character as long as the intermolecular forces strengthen, in such a way, the substance with the highest tendency to form the aforesaid bonds is the ethylene glycol, [tex]HOCH_2CH_2OH[/tex], due to its two hydroxiles in its structure.

Best regards.
