There's this problem that I saw in my Organic Chemistry book:
The reaction between $\ce{(CH3)3CH}$ and $\ce{Cl2}$ forms two products: $\ce{(CH3)2CHCH2Cl}$ (63%) and $\ce{(CH3)3CCl}$ (37%). Why is the ...

While using ChemDraw Professional 21.0.0.28 to construct some cyclic allenes and rotationally restricted biphenyls, I came across anomalous assignments of stereochemistry. [For the latest version of ...

The quantum yield for homolytic O-O cleavage of (CH$_3$)$_3$COOC(CH$_3$)$_3$ at $266$ nm is $0.21$. In one experiment, a pulsed laser of this wavelength was used to induce the formation of t-butoxyl ...

I am a mathematician now studying an introductory chemistry course.
Consider a liquid in a closed container, at (say) room temperature.
Then some of the liquid will vaporize. Then some of the ...

I am a mathematician and I want to understand the molar free energy model given in Kim and Sanders (2020) Equation (1), that is,
\begin{equation}
f(c,T) = RT \big(c \log(c) + (1-c) \log(1-c)\big) + \...

Which has higher boiling points among butan‐2‐ol (1) and 2‐methylpropan‐1‐ol (2)?
I know that branching decreases the boiling points, but I want to know how position of substituents affects the ...

From the Wikipedia article, the redox reaction for a voltaic pile is:
\begin{align}
\text{Oxidation:} && \ce{Zn &-> Zn^{2+} + 2e^-}\\
\text{Reduction:} && \ce{2H^+ + 2e^- &-&...

So I wanted to know what the reaction between sodium hydroxide and carbon dioxide can be, and upon research I got 2 answers. The first one is
$$\ce{CO2 + NaOH(aq) -> NaHCO3(aq)}$$
and the second ...

I know I should divide $\pu{g L-1}$ by the molar mass of the substance, but I don't seem to find the specific answer on Google. So just to be sure:
If I have $10^{-5}~\pu{g L-1}~\ce{Cu^2+}$ solution, ...

Sodium is more electropositive than hydrogen although they are in the same group.
Why is the electronegative value of hydrogen greater than sodium (metal)?

How do I type a simple chemical equation in Microsoft Word? I can do subscripts, but long arrows are more difficult. I can't get them to align with the text.
Also, I can't figure out how to put a ...

I've always been puzzled by this because my teachers happen to use only the KLMN method, but what is the difference between the KLMN and SPDF methods of finding electronic configuration?

How to prepare $\mathrm{0.1M}$ $\ce{I_2}$ solution.
I have found in books that it should be prepared in $\ce{KI}$ solution but none of them explains why? Please explain in detail not just the ...

If zinc is less reactive than sodium, then why does it still react with sodium hydroxide?

Can you answer these questions?

In the canonical ensemble the probability of finding an atom (or molecule) in its $i$-th energy state is given by the Boltzmann factor.
This probability is interpreted as the number of microstates ...

I'm a book and paper conservator, and a few years ago had four books to restore. Their endpapers were this gorgeous green silk, but they were badly dry rotted, and needed to be removed. I suspected ...
