Chemfig is an excellent LaTeX package that enables you to easily draw chemical structures. One needs to get used to the code chemfig “eats.” The basic code is simple, as can be seen from the following line of code:

\chemfig{[:30]--[::-60]--[::-60](=[::-60]O)-OH}

produces

Many more structures can be typeset using chemfig. Carbon rings and polymer brackets are easy to code and will be typeset beautifully. The following snippet of code

\chemfig{[:0]-[@{op,.5}]O-**6(---
(-C(-[::90]CH_3)(-[::270]CH_3)-**6(---
(-O-C(=[::90]O)-[@{cl,0.5}])
---))
---)}
\polymerdelim[height=20pt, depth=20pt, indice=\!\!n, delimiters={[]}]{op}{cl}

is typeset as

Chemfig can even typeset complete reaction mechanisms:
