Question

Identify the functional groups present in the following carbon compounds:

\[\begin{array}{cc} \phantom{..}\ce{H}\phantom{...}\ce{O}\phantom{...}\ce{H}\phantom{..}\\ |\phantom{....}||\phantom{....}|\\ \ce{H - C - C - C - H}\\ |\phantom{.........}|\\ \ce{H}\phantom{........}\ce{H}\\ \end{array}\]	\[\begin{array}{cc} \phantom{..}\ce{H}\phantom{...}\ce{H}\phantom{...}\ce{OH}\phantom{}\\ \phantom{}|\phantom{....}|\phantom{....}|\phantom{}\\ \ce{H - C - C - C = O}\\ \phantom{.}|\phantom{....}|\phantom{......}\\ \ce{H}\phantom{...}\ce{H}\phantom{.....}\\ \end{array}\]
(I)	(II)

Answer 1

Two common functional groups are carbonyl (C = O) and carboxyl \[\ce{(COOH)}\] groups.
