# Bond > in Functional Group

I'd like to get a bond represented by >. As an example, see the table where the ketone group is represented by >C=O (nonring). Is there a better way to write that other than the following?

>\ce{C=O}


# Package mhchem

> can be included inside \ce by using math, see section "Using Math, Variables" on page 8 of mhchem's documentation:

\documentclass{article}
\usepackage{mhchem}

\begin{document}
\ce{$>$C=O}
\end{document}


A more complicate version, which works with bold font:

\documentclass{article}
\usepackage{mhchem}

\begin{document}
\ce{$\hbox{\textgreater}$C=O}
\textbf{\ce{$\hbox{\textgreater}$C=O}}
\end{document}


# Package chemfig

Package chemfig can draw it as (kind of) molecule. Example with different bond lengths:

\documentclass{article}

\usepackage{chemfig}

\begin{document}
\chemfig{C(-[:150])(-[:210])=O}

• @mhchem Thanks for the information. I have added a version, which uses the text font version \textgreater of the greater sign, which honors a bold font. Aug 22 '15 at 6:29
