Why Is Hydrogen in HSO3- Connected to Oxygen Instead of Sulfur?

It's actually both, at least in solution. Bisulfite ion in solution tautomerizes, existing as an equilibrium of the isomer with hydrogen bonded to sulfur and the isomer with hydrogen bonded to oxygen. ...

Why does ammonium chloride form an ionic bond?

Quick Answer Explicit valence of $\ce{N}$ is four, $\ce{N}$ of $\ce{NH4+}$ cannot form another (covalent) bond with $\ce{Cl-}$. The chemistry of $\ce{NH4+}$, owing to similar size, charge, and ...

Why Is Hydrogen in HSO3- Connected to Oxygen Instead of Sulfur?

While in the specific case of bisulfite you were technically correct (at least some of the time, as Oscar Lanzi explains), the reason most sources show the hydrogen only bonded with the oxygen is ...

Lewis Structure of the Guanidinium Ion

You missed a sign. When you incorporate the charge into your electron count, you subtract positive charges and add negative charges because an electron is negatively charged. $4+[3×(5+2)]\color{red}{+}...

Non-octet structures of stable nitrogen compounds

Your comparison of the nitrogen oxides with phosphorus pentachloride is not apt. The former have unpaired electrons whereas the latter has multicener bonding with all electrons paired. These represent ...

Why Is Hydrogen in HSO3- Connected to Oxygen Instead of Sulfur?

To add to the excellent answer by Oscar Lanzi, according to Golding R. M. (1960),$^\text{1}$ based on UV spectroscopy results in aqueous solutions, the equilibrium is dependent on concentration, and ...

Why does ammonium chloride form an ionic bond?

As there is no bond between nitrogen and chlorine in ammonium chloride, it cannot be either ionic either covalent. Nitrogen bonding in an ammonium cation is fully saturated by four covalent bonds to ...

Why this Lewis structure for HNO3 nitric acid is wrong?

The structure isn't incorrect. It just has a high formation energy. Structure Heat of Formation ($\pu{kJ mol^{-1}}$) Reference 236.69 MolCalc -159.02 MolCalc Because of the low heat of formation ...

Is this a correct Lewis Dot structure for ozone?

Dear OP, by the way, that 'trioxygen' is dubbed ozone. For starters, the Lewis dot structure for ozone does not look like that. It is not a ring. This is explained in this link: Can ozone have a ...

Why this Lewis structure for HNO3 nitric acid is wrong?

Structures with nitrogen atom bound to several oxygen atoms are generally energy rich, which would be boosted by the stress of three-member ring. Such rings are generally unstable and reactive. Also, ...
