Answer #1

Answer: e) HOCH2CH2OH

a) is a ether, low boiling point and low viscosity

b) is dichloromethane has higher density but not viscosity

c) is ethanol has hydrogen bonding, hence we can expect a reasonable viscosity.

d) bromomethane is gas at room temperature

e) ethylene glycol has highest hydrogen bonding among given set. Remember general trend is higher the hydrogen bonded atoms present in the molecule then higher its boiling point as well as viscosity also.

Well known Glycerine is HOCH2(CHOH)CH2OH has 3 h-bonding.
