Why are amines more soluble than ethers in water?
For example, diethyl ether ($\ce{C2H5OC2H5}$) has a limited solubility of $6.05\rm~\frac{g}{100~mL}$ water at $25\rm~^\circ C$. However, diethylamine ($\ce{(C2H5)2NH}$) is a lot more soluble in water. ...

Hydrogen donor without hydrogen acceptor?
Is there a molecule that can donate a hydrogen to a hydrogen bond but not accept one? It would seem that since the donated hydrogen needs to be bonded to an electronegative atom, that electronegative ...

Hydrogen bonding in staggered vs eclipsed conformations
In my first semester of organic chemistry, we learned that staggered conformations have lower energy/higher stability.
However, my thought is that if you have interacting OH groups, the hydrogen ...

Do symmetric hydrogen bonds in neutral molecules exist?
As far as I know, there have only few truly symmetric hydrogen bonds been observed. Unquestionable is the existence of it in the bifluoride ion, $\ce{[F-H-F]-}$, see also here. There are a couple of ...

Why are trans fats worse than saturated fats?
Saturated fat molecules have no double-bonded carbons, so they are long and straight, which means they stack easier and tend to form solids at room temperature, and solids are better at forming ...

Hydrogen Bonding (with oxygen) - restricted to oxygen singly bonded to H or not?
I understand the following definition of a hydrogen bond from Merriam Webster:
an electrostatic attraction between a hydrogen atom in one polar
molecule (as of water) and a small electronegative ...

How many bonds can Hydrogen make?
Recently I saw a video which told me that Hydrogen has a valency of 1, i.e, Hydrogen can only bond with 1 other atom. But since hydrogen wants a complete shell, it can have 2 covalent bonds with 2 ...
