The question given above appeared in the 2016 Indian National Chemistry Olympiad (INChO). What I think is that the epoxide ring is being opened by a base-catalysed mechanism ($\mathrm{S_N2}$). I proposed the following few steps for this: The diisopropylamide ion, which is a very strong base, wo...

Some questions about the constant made me curious as to exactly how much the accepted value has changed over the years. I am pretty sure that I learned a rounded value of $6.023\times10^{23}$ about 1970 which would have been around the 50th edition. I know that sometime after that the accepted va...

I have the following table. I'd like to use the hyperlinked dates which follow the table inside the table. Is this possible? $$\begin{array}{|c|c|l|}\hline Year(s) & page & value \\ \hline 1969 & 50(footnote) & 6.022\,52(7)\times 10^{23}\\ \hline 1973 & 25 (17.3) & 6.022\,176(97) \times 10^{23} ...

I have studied this in my chapter atomic structure that when an electron changes its orbit from lower energy to higher energy state , it does not state in my book that it moves there but that it disappears.It just kind of reaches that orbit without crossing the path.We don’t know whether it move...

LPG and Candle wax both contain saturated hydrocarbon, yet LPG gives a clean white flame but a candle gives yellow flame with lots of smoke. Why so? I have read some answers on web which says that it is due to the insufficient supply of oxygen, so I tried burning candle beside LPG ( so there is n...
