there are 3 functional group that particpate in hydrogen bonding ﮼ On what basis do they participate
Homework Answers
Hydrogen bonding takes place when a hydrogen atom is attracted to a highly electronegative atom in another molecule. Hydrogen bonding takes place between hydrogen and either nitrogen, oxygen, or fluorine.
-OH, -FH, or -NH groups can only form hydrogen bonds.
Because of the difference in electronegativity, the H atom have a large partial positive charge and the N, O or F atom have a large partial negative charge.
