- Differences between H-H-O and H-O-H - Chemistry Stack Exchange
Therefore, the formula $\ce {HHO}$ is either a very idiosyncratic way of denoting a molecule of water (normally written $\ce {H2O}$ and occasionally $\ce {HOH}$, in order to emphasize its structure, i e , H-O-H), or it refers to oxyhydrogen, which isn't actually a molecule at all, but rather a mixture of hydrogen and oxygen gases (the molecules
- Why Is HOI a weaker acid than HOCl? - Chemistry Stack Exchange
$\ce {HOCl}$ is a stronger acid then $\ce {HOI}$ for similar reasons as why $\ce {HOI}$ is a stronger acid than $\ce {HOH}$ Because the electronegativity decreases $\ce {Cl > I > H}$ For the general schema of oxoacids $\ce {H-O-R}$, the more polarized bond $\ce {O-R}$ means the less polarized bond $\ce {H-O}$ and the weaker acid The weaker pulling of electrons by the oxygen atoms from the
- Configuration of a water molecule? - Chemistry Stack Exchange
The HOH bond angle for an isolated water molecule is accurately known to be 104 5° (104 52°±0 05° from Rotation‐Vibration Spectra of Deuterated Water Vapor J Chem Phys 24, 1139) In the liquid phase, values of 105 5° (calculated) and 106° (experimental) are reported in Structural, electronic, and bonding properties of liquid water from first principles J Chem Phys 111, 3572 The
- Do chemists refer to water as dihydrogen monoxide?
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 the terms dihydrogen monoxide or oxidane and do not intend to do so in a serious, scientific context Typically, one talks and writes about water, aqueous solutions and even uses a (traditional) term like brine
- organic chemistry - Why total heat of hydrogenation of 1,3 . . .
The relatively smaller Heat of hydrogenation (HOH) for benzene as compared to that for 1,3-cyclohexadiene is due to the aromaticity of the first Analyzing the thermochemistry is indeed among the first and perhaps more intuitive ways to present and quantifies aromaticity itself
- Which has stronger hydrogen bonds: water or ice?
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 liquid water In the first case, the decreasing $\ce {O-O}$ distance means that every pair of monomers experiences greater nuclear repulsion
- 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 number would come first for example:- H 2 O,CO 2,HF,etc But why is it that hydroxide is OH- and not HO-? Also why is methane CH 4 and not H 4 C?
- Why does hydrogen bonding require a lone pair? [closed]
Topological analysis of electron density in the HOH···CH4 complex by the AIM method showed that the parameters of the critical point of the bond between hydrogen and acceptor (carbon atom) for the O–H···C interaction are typical for Н-bonded systems (the magnitude of electron density at the critical point of the bond, the sign and
- Why isnt CH3OH basic if it contains OH? - Chemistry Stack Exchange
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 that doesn't mean that water is strongly basic
- Raman Spectrum of Water - Chemistry Stack Exchange
This is the Raman spectrum of water There is $\pu {1635 cm-1}$ Raman peak corresponding to $\ce {HOH}$ and $\pu {3410 cm-1}$ Raman peak corresponding to $\ce {OH}$ But why is there general nonzero
