Suppose we have to compare the $\mathrm{S_N2}$ reactivity order for cyclopropyl and cyclopentyl chloride. How can we do that?
I think that cyclopentyl should be more reactive towards $\mathrm{S_N2}$ because of larger bond angle and therefore lesser steric hindrance to the atttacking nucleophile...
I could not find any rule in Graphic representations (chemical formulae) of macromolecules (IUPAC Recommendations 1994) that would state that the bonds at the ends of the constitutional units must intersect the enclosing parentheses/braces. Only that they must be drawn:

Consider the possible values of $S$ and $L$ for carbon configuration $1s^2 2s^2 2p^2$ and the corresponding rapresentations with arrows indicating the spins (consider only $S=0,L=0$ and $S=0,L=2$, as for $S=1,L=1$ some are missing).
I can't understand which one of the two representations indic...
Well, not quite bucket, but large scale. The only annoying thing is its volatility, so it was always made as an Et2O solution kept in the freezer, and we'd have to determine the concentration by NMR, which was pretty trivial.
