Give both the systematic (IUPAC) name and the common name for the following compound:
\begin{matrix} O\,\,\,\,\,\,\,\,\,\,\, \\ CH_3CH_2\overset{||}{C} CH_2CH_2CH_3 \end{matrix}
ANALYSiS The compound is a ketone, as shown by the single carbonyl group bonded to two alkyl groups: an ethyl group on the left (CH_3CH_2—) and a propyl group on the right (—CH_2CH_2CH_3). The IUPAC system identifies and numbers carbon chains to indicate where the carbonyl group is located, counting in the direction that gives the carbonyl carbon the lowest number possible.
\begin{matrix} O\,\,\,\,\,\,\,\,\,\,\, \\ \underset{1}{C} H_3\underset{2}{C}H_2\overset{||}{\underset{3}{C}} \underset{4}{C}H_2\underset{5}{C}H_2\underset{6}{C}H_3 \end{matrix}
The common name uses the names of the two alkyl groups.
