Question

Ether and acetone should be kept at cool places why ?

Answer 1

ether and acetone both have a really very low boiling point and thus both of them are really very volatile substances.
Thus if they are kept exposed to the room temperature then they will readily evaporate due to unfavorable temperature.
Thus to be preserved and protected they are stored under really cool temperature.

Answer 2

Ether and acetone should be kept at cool places why

• They can easily evaporate at room temperatures.
• They take up the heat from the atmosphere and the molecules of acetone use this heat up to evaporate.
