An aqueous solution of methanol in water has vapour pressure :
a) equal to that of water
b) equal to that of methanol
c) more than that of water
d) less than that of water
pls explain...

An aqueous solution vapour pressure is more than that of water but less than that of methanol. This is due to solute-solvent interaction is more due to the formation of hydrogen bonding.
So option c is correct.
