As the manual mentions textmath will make all text math subject to previews. Since math mode is used throughly inside of LaTeX even for other purposes, this works by redefining $$,$$ and \$ and the math environment (apparently some people use that). Only occurences of these text math delimiters in later loaded packages and in the main document will ...

Compounds inside \schemestart and \schemestop are tikz nodes with names you can refer to. chemfig names them c1, c2, … but you can also give them own names. You can use this in \chemdraw to place the minus: \documentclass{article} \usepackage{chemfig} \usetikzlibrary{calc} \begin{document} \begin{center} \schemestart \chemleft[ ...

The answer is the same as in Drawing chemical reactions: Then CH3CHCH3 must be considered as one group of 6 atoms (C, H, C, H, C and H) where the bond is leaving from the third atom. You need to tell this to chemfig using the bond's optional argument <departure>: <bond>[<angle>,<length ...

The solution is simple: add | after \select: The character “|” forces splitting of the atom when it is encountered. Thus we can write C|{(CH_3)_3} to ensure that ChemFig separates just two atoms here: “C” and “{(CH_3)_3}”. Without \select_{Argomento='moto'} is considered one atom and the bond is centered. With | we have two atoms where the bond can ...
