  1. Differences between H-H-O and H-O-H - Chemistry Stack Exchange

    Jan 14, 2015 · To add to this, there are exceptions to the 'hydrogen only makes one bond' rule of thumb, in the form of unusual electron-deficient bonds as found for instance in boranes, however this does …

  2. 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, what is the …

  3. Estimation of the bond angle of water - Chemistry Stack Exchange

    Nov 24, 2015 · We know from experimental data that $\\ce{H-O-H}$ bond angle in water is approximately 104.5 degrees. If its two lone pairs were bonds (which is unfortunately impossible) …

  4. 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 used …

  5. Which of the following has a stronger hydrogen bonding: F-H- -O or F …

    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 cause is the high …

  6. 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 $\ce {O-O}$ distance and widening $\ce {HOH}$ angle tells us that ice has stronger hydrogen bonds than …

  7. 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 lower atomic …

  8. Why does water split into ions? - Chemistry Stack Exchange

    Sep 20, 2017 · What is the property of a water molecule that allows it to split into $\\ce{OH-}$ and $\\ce{H+}$ ions? And subsequently, why - when these ions are attracted towards each other in a …

  9. organic chemistry - What is the reason for Hyperconjugation ...

    Mar 3, 2025 · Hyperconjugation is when a sigma-bonded hydrogen and carbon weaken their bond and the single bond develops partial character while the initial double bond develops partial character …

  10. 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 molecules surround …
