Question

Explain in biochemical terms why methane (CH₄), which is of similar molecular weight as water, has a drastically lower boiling point compared to water.

Answer 1

water has a higher boiling point because the hydrogen bond form among water molecules are strong er than the vanderwaals force of attraction among methane molecule ,. more energy needed to break the hydrogen bond in water and allow the molecules to escape methane is non polar

each molecule of water has a possibility of forming 4 h bonds each hydrogen atom can bond to another water molecule . each o2 in water has 2 lonepairs that can interact with the electron defficient hydrogen atoms of 2 different neighbouring water molecules . thus forming large net work of hydrogen bonding and this is the cause for high boiling point of water
