<description>Find all nonsubstituted naphtalenecarboxylic acids.</description>

<query>
<comment>The first aproach is to find 1-naphtalenecarboxylic acid and 2-naphtalenecarboxylic acid separately</comment>
<subquery hits="41" pict="ex8A">1-naphtalenecarboxylic acid</subquery>
<subquery hits="25" pict="ex8B">2-naphtalenecarboxylic acid</subquery>
<subquery text=".Q1 or.Q2" hits="66">putting the two parts together</subquery>

<comment>If you are too lazy to draw them both you can use this aproach</comment>

as a side effect this removes hits with deuterium substitution</subquery>
