- 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
- 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?
- Why does water dissociate to H3O+ and OH- rather than H+ and OH-?

- 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:
- Is LiOH a weaker base than NaOH? - Chemistry Stack Exchange
