Question

Arrange the following compounds in order of increasing volatility of acetone, methanol, ethylacetate, 1-butanol and water, give some basis in the arrangement

Answer 1

Answer:

water < 1-butanol < methanol < ethylacetate < methanol

Explanation:

Volatile organic compounds (VOCs) are low-molecular-weight organic compounds that easily evaporate at room temperature. In organic compounds, lesser is the hydrogen bonding present in a compound or substance more will be its volatility. This is because hydrogen bond is a strong bond and to break it we need higher amount of energy.

Acetone has least hydrogen bonding so it is the most volatile substance. Whereas water has strong hydrogen bonding therefore, it is least volatile.

water < 1-butanol < methanol < ethylacetate < methanol
