write the molecular formula of first six homologues of homologous series of aliphatic aldehydes
Answers
Explanation:
Complete step by step solution:
First, let us know about the aliphatic compounds.
The hydrocarbons are of two types- the aliphatic and the aromatic.
The aromatic compounds are the one which is cyclic, planar and follow huckel’s rule. The other compounds are the aliphatic one. These may be cyclic or linear chains but do not possess properties of aromatic compounds.
The homologous means that the increasing series.
The first aldehyde is formaldehyde. It has structure-
HCHO
In the homologous series, one carbon unit increases at each step. So, the second member of aliphatic aldehyde will be two carbon molecule. The molecule is acetaldehyde. It has structure -
CH3CHO
After this is the third member of the homologous series. It will contain three carbon units. The molecule will be propionaldehyde. It will have structure -
CH3CH2CHO
It is also called as propanal.
