Re: hydrogen bonds
Hydrogen bonding occurs between a positive dipole hydrogen and a negative dipole F, O, or N! :)

Re: hydrogen bonds
Hydrogen bonds form between a hydrogen attached to a highly electronegative atom (N, O, or F) and another N, O, or F on another molecule.

Re: hydrogen bonds
Also, I think this was mentioned briefly in the textbook, but that N, O, or F atom should also have lone electron pairs available for H-bonding

Re: hydrogen bonds
Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen. These elements are so electronegative that they take majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient. The H atom nearly acts as a bare proton, leaving it very attracted to lone pair electrons on a nearby atom.

Re: hydrogen bonds
My high school chemistry teacher taught us that in order to hydrogen bond, a hydrogen must be directly attached to a FONny molecule (F, O, or N). Then, that hydrogen can bond with another F, O, or N. Hopefully that helps you remember!

Re: hydrogen bonds
Hi, hydrogen bonds can occur between a partially positive hydrogen atom (that is, a hydrogen already bonded to an electronegative atom) and a N, O, or F.

Re: hydrogen bonds
Hi! A hydrogen bond can form between a partially positive hydrogen atom and F, O, or N. My teacher in high school told us to think about E.T. and the scene where he says 'FON' Home (phone home). Hope that helps you remember!

Re: hydrogen bonds
In high school, we used the acronym FON to memorize which elements can form hydrogen bonds with hydrogen! Also, there needs to be a partial positive and a partial negative dipole !

Re: hydrogen bonds
Hello! Hydrogen bonds usually tend to form with Nitrogen, Oxygen, and Fluorine. Additionally, to be able to form hydrogen bonds, there must be a partial negative and partial positive dipole. The positive end of a molecule is attracted to the negative end of another molecule. (Just think about the "Opposites attract"!) I hope this helps!

Re: hydrogen bonds
Hydrogen bonds usually form with FON or fluorine oxygen and nitrogen and are usually relatively strong bonds

Re: hydrogen bonds
Some people have mentioned FON and it's a great way to remember that hydrogen bonds form with fluoride, oxygen, and nitrogen!

Re: hydrogen bonds
In order to see which molecules can form H bonds, you need to make sure that the stronger atom (O for instance) has a negative charge while the H atom has a positive charge.

Re: hydrogen bonds
Hydrogen bonds occur between a H atom in a polar bond and unshared electron pair on a nearby, small atom with a high electronegativity. These atoms are usually F, O, and N.

Re: hydrogen bonds
Hydrogen bonds are a very strong bond between hydrogen and other elements of high electronegativity and can only be bonded by F, N, and O

Re: hydrogen bonds
Hydrogen bonds are formed when a hydrogen atom attaches to highly electronegative atoms, which are Fluorine, Oxygen, and Nitrogen. I usually memorize them with the abbreviation "FON".

Re: hydrogen bonds
Hydrogen bonding occurs with fluorine, oxygen, and nitrogen. This is because these elements are so electronegative that partially positive and partially negative charges can form when hydrogen is attached to these molecules, thus creating adequate conditions for hydrogen bonding.

Re: hydrogen bonds
Hydrogen bonds are considered to be polar bonds (unequal sharing of e-) that result when a hydrogen atom bonds with a very electronegative element. Those electronegative elements are fluorine, oxygen, and nitrogen.
