Bending of water and methanol towards a charged objects
I just had a question about why does water, methanol or any other polar substances tend to bend towards the charged object.
I think it is because of a slight dipole dipole movement between the ...

Why is HCl not considered to have hydrogen bonding?
A molecule that has hydrogen bonding usually follows these two premises.
1.) There is a hydrogen atom involved
2.) Hydrogen must be bonded to a highly electronegative element which are nitrogen ($\ce{...

Why does the gauche conformation of ethane-1,2-diol show hydrogen bonding?
Why does the gauche conformation of ethane-1,2-diol show hydrogen bonding even though there is no 6-membered ring system? If we don't consider one of the $\ce{H}$ (which is what is usually done), then ...

Why is a ketone not capable of hydrogen bonding among themselves?
The ketone has one oxygen atom in it and there are two lone pairs hanging out, both of which make it seemingly capable of hydrogen bonding. But in reality it is not.
Did some research and found this ...

Hydrogen bond comparison
How do you compare the strength of H bonds when it's the same atom on both sides of the H? Like $\ce{N-H\bond{...}N}$ vs $\ce{F-H\bond{...}F}$? Is one still stronger than the other, or are they both ...
