Why is it that butanol is capable of hydrogen bonding? When I look at the Lewis structure, I noticed that only H's lie at the end of the molecule rather than F, N, or O?
Thank you!

Re: Butanol and Hydrogen Bonding
I just googled the Lewis structure and found that the oxygen lies between a carbon and hydrogen, therefore allowing it to hydrogen bond. Are you sure you have the write lewis structure?

Re: Butanol and Hydrogen Bonding
There is one hydrogen atom in butanol that is connected to an oxygen atom at the end of the molecule, which is what allows for hydrogen bonding to occur (since O is in the NOF group, and a hydrogen atom bound to one of these three atoms results in the molecule being able to hydrogen bond).

Re: Butanol and Hydrogen Bonding
Hi Jack, in the butanol molecule, even though H's lie on the outsides of the structure, there is one H atom bonded to an O atom (which like mentioned above is in the NOF group), which allows for hydrogen bonding from the H to another molecule that also forms hydrogen bonds. Hope this helps!

Re: Butanol and Hydrogen Bonding
Looking at the butanol structure, while there is a large carbon chain, at the end is an OH. Because of the electronegativity difference, the hydrogen is slightly positive and the oxygen is slightly negative, meaning hydrogen bonds can form.

Re: Butanol and Hydrogen Bonding
Hi! Using the Lewis structure, you find that the oxygen lies between carbon and hydrogen, allowing a hydrogen bond to be formed with an OH bond at the end.

Because of the OH at the end of the chain, the molecule has a slightly positive hydrogen and a slightly negative oxygen. This means hydrogen bonds can form.
