As the molecules tend to become more viscous the more OH groups then I would put the order of increasing viscosity as
Propanol,
Propanediol,
Propanetriol,
Arrange the following compounds in order of increasing viscosity: Propanol, CH3CH2CH2OH; Propanediol, CH3CH(OH)CH2OH; Propanetriol , HOCH@CH(OH)CH2OH
