\arrow(--plus){0}[,.1]
\+
\arrow{0}[,.1]
\chemfig{@{C}\lewis{4.,C}H_3}
\arrow
\chemfig{\lewis{0.2:4:6:,Cl}}
\chemsign{+} \chemfig{\lewis{2:4:6:,Cl}-CH_3}
\schemestop
\chemmove{
\path (plus) ++(45:4mm) coordinate (nb) ;
\draw[elmove=left]
(b) ..controls +(-90:7mm) and +(-90:7mm) .. (Cl1) ;
\draw[elmove=left]
