Answer the following question:
What is called homologous series? Give any two of its characteristics?
a. A general molecular formula is used to represent them. For example, (\(C_nH_{2n + 2}\)), , (\(C_nH_{2n}\)) and alkynes (\(C_nH_{2n – 2}\)).
b. A common method can be used to prepare all of the members in a homologous series. For example, aldehydes can be prepared by . \(RCH_2OH\xrightarrow{K_2Cr_2O_7} R-CHO\)
