Which of the following compounds shows strongest hydrogen bonding? A H F B H2 O C N H3 D C H3 O H
Among the F, O and N , Fluorine has the higher value of electronegativity, this is the reason that fluorine can form the strongest hydrogen bond with the H atom of another molecule.Just take an idea from the value of energy of hydrogen bond that is formed with HF, H 2 O and NH 3 HF 10kcal/mol H 2 O 7Kcal/mol NH 3 2Kcal/molmeans to break the hydrogen of one mole HF molecules, 10Kcal energy is required.So the correct option is [A].
