which statement best explains why water has a higher boiling point than ethane?\no ethane molecules are smaller than water and can move faster.\no water molecules need relatively less heat energy to move.\no water molecules form hydrogen bonds, which cannot be broken by heating water.\no ethane molecules have no hydrogen bonds and need less energy to separate.

Answer

Brief Explanations:

Hydrogen bonds are strong intermolecular forces. Water has hydrogen - bonding due to the electronegative oxygen and hydrogen atoms, while ethane has only weak van der Waals forces. More energy is needed to break the stronger hydrogen - bonds in water, resulting in a higher boiling point.

Answer:

Ethane molecules have no hydrogen bonds and need less energy to separate.
