Which compound has the highest boiling point? explain your reasoning. ch4 or ch3ch3

question 28 options:

ch3ch3. it has a greater mass and number of electrons which causes greater dispersion forces and a higher boiling point.

ch4 has stronger dispersion forces compared to ch3ch3 which leads to a higher boiling point.

ch3ch3. it is flatter which causes greater dispersion forces than ch4.

ch4 has a lower mass compared to ch3ch3 which leads to a higher boiling point.

The correct answer t is ; has a lower mass compared to which leads to a higher boiling point.

Explanation:

Boiling point of alkanes increases with increase number of carbon atoms in the chain.

This is because along with increase in carbon atom molar mass of alkane also increases by which surface area of molecule increases which further results in increase in weak vander wall forces among the molecule. Due to this molecules associates strongly with each other and boils at high temperature
