(A)INTRODUCTION.
Alkanoic acids belong to a homologous series of organic compounds with a general formula Cn H2n+1 COOH and thus -COOH as the functional group
Alkanoic acids like alkanols /alkanes/alkenes/alkynes form a homologous series where:
(i)the general name of an alkanoic acids is derived from the alkane name then ending with “–oic” acid.
(ii) the members have R-COOH as the functional group.
