Differences between H-H-O and H-O-H - Chemistry Stack Exchange 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 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 . . . 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 gene
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?
Estimation of the bond angle of water - Chemistry Stack Exchange 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 impossible) also O−H O H bonds and a perfect tetrahedron resulted, then VSEPR theory would predict that the bond angle would be 109 5 degrees - this number can be easily derived using the geometry of a tetrahedron However, how would
Configuration of a water molecule? - Chemistry Stack Exchange As shown by Uncle Al there is some (old) experimental data on the bond angle of water in this article: Shibata and Bartell J Chem Phys 42, 1147 (1965) For water in vacuum they find: For HX2O H X 2 O: r_g (OH) = 0 976±0 0030 Å, mean HOH angle α_g = 107 2°±3° This means that there is no statistically significant deviation from the value at atmospheric pressure
Why Is HOI a weaker acid than HOCl? - Chemistry Stack Exchange HOCl H O C l is a stronger acid then HOI H O I for similar reasons as why HOI H O I is a stronger acid than HOH H O H Because the electronegativity decreases Cl>I>H C l> I> H For the general schema of oxoacids H−O−R H O R, the more polarized bond O−R O R means the less polarized bond H−O H O and the weaker acid The weaker pulling of electrons by the oxygen atoms from the atom
Why isnt CH3OH basic if it contains OH? - Chemistry Stack Exchange These also feature OH O H groups, they are even commonly written that way, but are about as acidic or basic as water (HOH H O H) is So the question may be why did you get taught that OH O H is basic? Well strictly speaking, it is not the OH O H hydroxy group that is basic but the OHX O H X hydroxide ion
Do chemists refer to water as dihydrogen monoxide? Is the name "Dihydrogen monoxide" actually what chemists would use to refer to HX2O H X 2 O (assuming there was no common name, "water")? Of course, this is all over the internet I'm a little skeptical though because the similar chemical HX2S H X 2 S is called "hydrogen sulfide", not "dihydrogen monosulfide"
How do hydrogen bonds break the ionic bonds of a crystal lattice? 2 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 both the Na + and Cl - ions The interaction there is dipole-ion Na-OH 2 and Cl-HOH
Why does the hydroxide ion have a negative charge? In a sense, you are overthinking it OH- has a negative charge, simply because it has a negative charge (it has one more electron than it has protons) There could also be an OH molecule with a negative 2 charge, but thats incredibly unlikely Bonds come into play after you know the number of electrons a molecule has
