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 , ), or it refers to oxyhydrogen, which isn't actually a molecule at all, but rather a mixture of hydrogen and oxygen gases (the molecules $\ce
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
Estimation of the bond angle of water - Chemistry Stack Exchange 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) also $\\ce{O-H}$ bonds and a
Which of the following has a stronger hydrogen bonding: F-H- -O or F-H- -F? 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 seperation of partial charge, which is maximum in H---F bond Similarly comparing corresponding say O-H and and F-H the latter will be more polar leading to stronger interaction
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
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
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 water split into ions? - Chemistry Stack Exchange 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 neutralisation re
How to determine the acidity or basicity of dissolved salts? Assuming your question is how to determine the acidity or basicity of salts Acidic Salt: A salt formed between a strong acid and a weak base is an acid salt $$\ce {HCl + NH4OH -> NH4Cl + HOH}$$ The $\ce {NH4Cl}$ is an acidic salt and if it dissociates it will be acidic Basic Salt: A basic salt is formed between a weak acid and a strong base $$\ce {NaOH + HAc -> NaAc + HOH}$$ The Sodium
