Arrange the liquids pentane (ch3ch2ch2ch2ch3), pentanol (ch3ch2ch2ch2ch2oh), and pentanal (ch3ch2ch2ch2cho) in order of decreasing viscosity, surface tension, and boiling point. rank from highest to lowest viscosity, surface tension, and boiling point. to rank items as equivalent, overlap them.

According to decreasing viscosity = pentanol > pentanal > pentane.

surface tension =  pentanol > pentanal > pentane.

Boiling point = pentanol > pentanal > pentane.

Explanation:

pentane (CH3CH2CH2CH2CH3), pentanol (CH3CH2CH2CH2CH2OH), and pentanal (CH3CH2CH2CH2CHO) in order of decreasing viscosity, surface tension, and boiling point. They all have same sequence in which they are in order hydrogen bonding > dipole dipole interactions > van der waals dispersion forces.

Surface tension is the property of  liquid's surface that resist the force and caused by the unbalance forces. Viscosity is related to  liquid's  resistance to being moved. This is caused by the friction between molecules and Branching decreasing the boiling point.
