Ethanol and Water Hydrogen Bonding Help
Hi guys, just a little confused
So in hydrogen bonding between ethanol and water
As ethanol has one slightly negative oxygen molecule and one slightly positive hydrogen atom
But water
Has 2 slightly negative oxygen lone pairs
And 2 slightly positive hydrogen atoms
There is always one lone pair free in the alcohol and water solution
What effect does this have? If any?

None.
There is some hydrogen bonding between ethanol and water and also between water and water. There is likely some between ethanol and ethanol also.
The bonds are not permanent in that they are formed and broken at room temperature.
If H-bonds were not labile then water would be a solid at RT
Are you trying to compare the magnitude of the intermolecular forces between pure ethanol and pure water (and not a water/ethanol mixture)? If so, then as you've noticed ethanol is unable to form as many simultaneous hydrogen bonds as water can - so despite the greater RMM of ethanol, it has a lower boiling point than water.
