- 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
- organic chemistry - Why total heat of hydrogenation of 1,3 . . .
A) Cycloexene HOH = -120 kJ mol B) 1,4-Cycloexadiene HOH = -240 kJ mol C) 1,3-Cyclohexadiene HOH = -232 kJ mol D) Benzene HOH = -208 kJ mol While for B the HOH is about double as compared to that of cyclohexane and thus is according to the assertion in the question, the conjugation in C does results in a "lower than expected" value
- 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
- Which has stronger hydrogen bonds: water or ice?
In ice Ih, the average $\ce{O-H}$ bond length is $\pu{1 01 \AA}$ and the $\ce{HOH}$ bond angle is $109 5^\circ$ The trend that has been observed experimentally is that in going from the gas-phase water monomer, through the clusters, to the liquid, and finally to ice, the bond angle slowly increases to this tetrahedral value
- Do chemists refer to water as dihydrogen monoxide?
No, it's not The "dihydrogen monoxide" name is used as part of a hoax In the scientific community, there are chemical names for water, and which one is used in the literature generally depends on how it interacts with something else (hydroxic acid and hydrogen hydroxide were two I heard most often in acid-base reactions)
- 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 background in intensity? What caused it? This is taken using 532nm wavelength raman system:
- Why isnt CH3OH basic if it contains OH?
Or take alcohols such as methanol ($\ce{H3C-OH}$) or ethanol ($\ce{H3C-CH2-OH}$) These also feature $\ce{OH}$ groups, they are even commonly written that way, but are about as acidic or basic as water ($\ce{HOH}$) is So the question may be why did you get taught that $\ce{OH}$ is basic?
- thermodynamics - How do hydrogen bonds break the ionic bonds of a . . .
So, on average, the ions will leave the crystal and enter the liquid (until their concentration is so high that equilibrium is established between the two phases) So, while it is true that HOH Cl bond can be called a H-bond, thinking about it this way has no obvious advantage as far as I can see The dipole-ion interactions that are
