Consider the following organic compounds :
(i) H-C-C-C=O, with three H atoms on the first carbon, two H atoms on the second carbon, and the third carbon double-bonded to O (i.e. an aldehyde group)
(ii) H-C-C=O, with two H atoms on the first carbon, and the second carbon double-bonded to O with one H (an aldehyde group)
(a) Name the functional group present in their compounds.
(b) Write the general formula for the compounds of this functional group.
(c) State the relationship between these compounds and draw the structure of any other compound having similar functional group.
Solution
(a) Aldehyde
(b) CnH2n+1CHO / R–CHO
(c) They are homologues.
