For which of the following parameters the structural isomers and would be expected to have the same values? (Assume ideal behaviour)
Heat of vaporisation
Vapour pressure at the same temperature
Boiling points
Gaseous densities at the same temperature and pressure.
As we learnt in
Physical properties of ether -
– Insoluble in water except dimethyl ether.
– Show dipole moment due to C - O polar bond.
– Boiling points of ether are lower than isomeric alcohol.Due to the presence of H-bonding in alcohol.
-
All the parameters will be different except the gaseous densities due to the presence of H-Bonding in alcohol which is absent in ether
