Which of the following liquids would have the highest viscosity at room temperature? 1) CH3OCH3
2)CH2Cl2
3) C2H5OH
4) CH3Br
5)HOCH2CH2OH

The liquid which would have the highest viscosity at room temperature is: Choice 5): HOCH2CH2OH.

Discussion:

The compound HOCH2CH2OH, named ethylene glycol relative to the other compounds has more hydrogen bonding.

By convention, an increase in the number of hydrogen bonds of a compound means an increase in the viscosity.

Hydrogen bonds are characterized by the of hydrogen with electronegative elements such as Oxygen, Nitrogen etc.

The compounds with the highest amount of Hydrogen bond is therefore; HOCH2CH2OH.

5)HOCH2CH2OH

Explanation:

This is also known as ethylene glycol. An increase in hydrogen bonds of a compound means an increase in the viscosity. Hydrogen bonds occur as a result of bonding with electronegative elements such as Oxygen, Nitrogen etc.

The compounds with the highest amount of Hydrogen bond represents the one with the highest viscosity which is B) HOCH2CH2OH
