Question

which has higher Vapour pressure -Dimethyle ether or Ethanol. Justify
No spam please!!!!!!!

Answer 1

Answer:

Diethyl ether has higher vapour pressure than ethyl alcohol.

The alcohols molecules are linked to each othe with strong attraction force of H bonding while there is only the weak dipole dipole force between the molecules of diethyl ether. So as the the result , the ether molecules are less bounded to each other than the molecules of alcohol.

So it's vapour pressure is high as a result the boiling point of ethers are also lesser than the alcohols.
