Answer:
Diethyl ether
Explanation:
vapor pressure - the pressure exerted by the gaseous molecules on the walls of the container , is called its vapor pressure.
The compound with higher boiling point , will have lower vapor pressure ,
and the compound with lower boiling point , will have higher vapor pressure.
Hence, Boiling point and vapor pressure have inverse relation.
The vapor pressure and boiling point both, depends on the inter molecular interactions , i,e, the interaction between the molecules.
Since, the compound with stronger inter molecular interactions, will not easily convert to gas, hence will have higher boiling point between , therefore , its vapor pressure would be less.
But the compound with less inter molecular interactions , can easily vaporize to convert to gaseous state and hence will have lower boiling point, therefore, its vapor pressure would be higher .
Among all the options , diethyl ether have lowest boiling point , hence, will have highest vapor pressure , at room temperature.
