Differences between H-H-O and H-O-H - Chemistry Stack Exchange
Jan 26, 2013 · Therefore, the formula HHO H H O is either a very idiosyncratic way of denoting a molecule of water (normally written HX2O H X 2 O and occasionally HOH H O H, in order to …
organic chemistry - Why total heat of hydrogenation of 1,3 ...
Jan 29, 2019 · I'm told that heat of hydrogenation (HOH) is directly proportional to number of π bonds and inversely proportional to stability. So, is the aromaticity responsible for this? Also, …
Estimation of the bond angle of water - Chemistry Stack Exchange
Nov 24, 2015 · We know from experimental data that H−O−H H O H bond angle in water is approximately 104.5 degrees. If its two lone pairs were bonds (which is unfortunately …
Do chemists refer to water as "dihydrogen monoxide"?
Feb 17, 2014 · Like most of the other professionals answering here, I've given a couple of talks on international conferences and published some articles in peer-reviewed journals. I have never …
Why is it OH- and not HO-? - Chemistry Stack Exchange
I am told that in a chemical equation the metal comes first and then the non metal. for example MgO, ZnSO 4,etc. But when both the elements are non metals or metals, the one with the …
Which has stronger hydrogen bonds: water or ice?
May 6, 2018 · So, finally, I feel we have said enough to explain why the knowledge that a shrinking O−O O O distance and widening HOH H O H angle tells us that ice has stronger …
Which of the following has a stronger hydrogen bonding: F-H- -O …
Aug 8, 2020 · F---H---F is stronger. This is an example of hydrogen bonding. More the partial charges generated on each atom better the interaction. The hydrogen bond is an effect. The …
Why isn't CH3OH basic if it contains OH? - Chemistry Stack …
A pretty common mistake to make when you're first learning to identify acids and bases: you can't just assume that everything with an OH will be basic. I can rewrite water as $\ce {HOH}$ but …
How do hydrogen bonds break the ionic bonds of a crystal lattice?
Your presumption that it is hydrogen bonding that breaks the ionic bonds is wrong. Forget H-bonds. It is true that they exist in both pure water and in a sodium chloride solution. Water …
Configuration of a water molecule? - Chemistry Stack Exchange
Apr 29, 2014 · The linked Google search mainly finds "Why is the bond angle of water 104.5∘ ∘ and not 109.5∘ 109.5 ∘. If using the VSEPR model, the nonbonding electron domains on water …
