Question

Next homologue of propanoic acid c2h5cooh

Answer 1

Explanation:

all homologues of a series have the same general formula

the higher homologue of ch3oh--methanol is ch3ch2oh--ethanol

the higher homologue of ch2 = ch2 --ethane is ch3ch=ch2--propene

Answer 2

The next homologue of propanoic acid is $C_3H_7COOH$.

• Homologous series is defined as the sequence of compounds that have the same functional groups and similar chemical properties.
• The members of the homologous series differ by $-CH_2$ unit.
• Thus the next homologue of propanoic acid has $-CH_2$ unit extra from $C_2H_5COOH$. Thus, the next homologue is $C_3H_7COOH$ or butanoic acid.
