I am trying to do the mechanism shown in the image. I am stuck in the second molecule. I don't know how to use brackets properly. I also need to put the asterisk as an exponent. enter image description here

  • The benzophenone radical is not a polymer, so no need for \polymerdelim here. You could get away with using \chemleft[ and \chemright] as for example shown here: https://tex.stackexchange.com/a/354474/134144 or here: https://tex.stackexchange.com/a/59820/134144 – leandriis Feb 14 '21 at 20:22

\documentclass[border=5mm]{standalone}
\usepackage{chemfig}

\begin{document}

\schemestart
\chemfig{[:-30]*6(=-=(-C(=[6]O)(=[2,,,,draw=none]\phantom{O})-*6(=-=-=-))-=-)}
\arrow{->[$h\nu$]}[,1.5]
\chemleft[\chemfig{[:-30]*6(=-=(-C(=[6]O)(=[2,,,,draw=none]\phantom{O})-*6(=-=-=-))-=-)}\chemright]
\schemestop
\chemmove{
    \node at ([shift={(3pt,-2pt)}]c2.north east) {$\ast$};
