H bonding

[nshahwan 1L]

This is just a clarification question, but when looking at a molecule and determining the points of hydrogen bonding, we are supposed to count each lone pair as well as each hydrogen bonded to NO or F correct?

Yes, when determining points of hydrogen bonding, lone pairs are also considered if it is on an N, O, or F as well as the hydrogens since the hydrogens will form a bond with those electronegative atoms.

Yes, it is also important to understand that hydrogen atoms bonded to carbon atoms are not counted when determining possible hydrogen bonding sites.

Why are hydrogen atoms bound to Carbon atoms not considered in determining hydrogen binding sites?

Why are hydrogen atoms bound to Carbon atoms not considered in determining hydrogen binding sites?

They are not considered because hydrogen bonding is a special form of dipole-dipole that only attracts to another molecule’s N, O, or F atoms. C is not included in here, therefore it does not occur!
