What is the chemical structure / hybridization of sulfuric acid?
Aug 27, 2012 · In the $\ce{H2SO4}$ molecule, two bonds are simple covalent ($\ce{S-OH}$ ones), and two are dative ($\ce{S-O}$ ones). A common concept of electron unpairing to my knowledge is proved broken by quantum chemistry calculations and spectral experiments for hypervalent compounds of $\ce{P}$ and $\ce{S}$.
Lewis Structure For H2SO4 - Chemistry Stack Exchange
Dec 22, 2017 · The best ring structure I could find looks like this (a distorted octahedral shape) and is estimated to have a $\Delta H_f^0$ = +33.05 kcal/mol. The O-O-S ring angles are ~65°. The lowest energy geometry is the traditional $\ce{H2SO4}$ Lewis structure, estimated at $\Delta H_f^0$ = -177.88 kcal/mol.
How is (SO4)^2- Charged if S and O all are Neutral Themselves?
Oct 14, 2015 · There are partial charges on the S and the O in SO4[2-], the Sulfate ion. Sulfate ions are found in sulfuric acid = H2SO4, which ionizes into SO4[2-] + 2 H+. Oxygen is electro-negative. It has a partial negative charge. Think of water = …
Why is magic acid a superacid? - Chemistry Stack Exchange
Aug 19, 2014 · Acidity is strongly dependent on the strength of the proton-conjugated-base bond. Basically stating, the weaker the bond, the higher is the acidity. All currently known superacids operate on this principle and " " is one of the strongest. The reason for the extraordinary acidity is the high potency of as a lewis acid.
inorganic chemistry - What is the nature of the oxide of boron ...
Feb 10, 2014 · The most common oxide of boron is boron trioxide, BX2OX3 B X 2 O X 3, which is the anhydride of boric acid: HX3BOX3 HBOX2 +HX2O H X 3 B O X 3 H B O X 2 + H X 2 O. 2HBOX2 BX2OX3 +HX2O 2 H B O X 2 B X 2 O X 3 + H X 2 O. net 2HX3BOX3 BX2OX3 +3HX2O net 2 H X 3 B O X 3 B X 2 O X 3 + 3 H X 2 O. As the anhydride of an acid, boron trioxide is acidic.
safety - How does sulfuric acid react to heating? - Chemistry Stack ...
Oct 11, 2016 · The decomposition of $\ce{H2SO4}$ to $\ce{H2O}$ and $\ce{SO3}$ is predominant between $400$ and $700\ \mathrm K$. The formation of a small amount of gaseous sulfuric acid can be observed. Above $673\ \mathrm K$, the equilibrium constant of the reaction R1 becomes higher than 1 and increases rapidly. $$\ce{H2SO4 <=> H2O + SO3}\tag{R1}$$
How does H2SO4 dissociate? - Chemistry Stack Exchange
Jun 17, 2018 · Apologies for this extremely basic question, I'm just beginning with Chemistry so please don't be too harsh on me. My book says that sulfuric acid, $\ce {H2SO4}$, dissociates in its ions following this reaction: $$\ce {H2SO4 -> H2^+ + SO4^ {2-}}$$. My question is, why can't the dissociation reaction happen like this: $$\ce {H2SO4 -> 2H^+ +SO4 ...
inorganic chemistry - How do copper sulphate and the like change ...
May 29, 2012 · This is a compound that wants water so badly that it willy synthesize water right out of the hydrogen and oxygen bonded into proteins and carbohydrates, leaving only charred carbon. Ironically, the actual acidity of concentrated (vs hydrated) $\ce{H2SO4}$ is quite moderate, comparable to that of vinegar.
organic chemistry - Nitrobenzene - Aromatic Substitution …
May 3, 2019 · I haven't been able to find much about EAS reactions of nitrobenzene online, hence I come to Chem SE, seeking data and sources. The reactions of interest are: 1.Friedel Crafts Alkylation, Acylation. 2.Nitration (concentrated sulphuric and nitric acid) 3.Sulphonation (fuming sulphuric acid) 4.Halogenation in presence of Lewis acids etc.
Significance of shapes of Conical flask and Kjeldahl flask
Apr 5, 2020 · This heating would cause splash-back, which is a treat because of conc. $\ce{H2SO4}$. Thus, along with his famous method, Kjeldahl had also developed a piece of laboratory equipment he developed in 1888, which bares his name as well, Kjeldahl's flask.
