For which molecule in each of the following pairs would you expect hydrogen bonding, in a sample of the pure substance, to be more significant as a contributing factor to the attractive intermolecular interactions?
a) (CH2OH)2 and CH3CH2OH (My answer: (CH2OH)2)
b) CH3CHO and CH3CO2H (My answer: CH3CHO)
c) H20 and NH3 (My answer: H20)
d) NH3 and NH2OH (My answer: NH2OH)
I've provided my original answers, which are incorrect and I'm confused as to why they're incorrect.
Homework Answers
(a)(CH2OH)2 is expected to show more hydrogen bonding as it has two hydroxyl groups attached to it.This molecule is glycol.
(b)CH3COOH will show more hydrogen bonding as it can show intramolecular and intermolecular hydrogen bonding.The hydrgen bonding takes place between F,O,N and H atom.Acetic acid has both of them.
c)H2O will show strong hydrogen bonding as hydrogen bonding strength increases will increase in electronegativity.
d) NH2OH has both atom O and H , thus capable of more hydrogen bonding.
