Respuesta :
In case of saturated hydrocarbons the boiling point increases with increase in number of C chain and decreases with branching
C₄H10 has greater number of Vander waal's interaction and will have higher boiling point as compared to C₂H₆
C₂H₆ and C₄H10 both are non polar
C₂H₆ is smaller molecule and weak dipole forces
C₂H₆ has higher vapor pressure
What is Vapor pressure ?
Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.
