Question

What is the basicity of propanoic acid c2h5cooh

Answer 1

Basicity refers to no of replaceable hydrogen atoms specially attached to the oxygen atom.

Here in propanoic acid the hydrogen attached to oxygen is only one thus it's basicity is 1

Hence the answer is 1

Answer 2

The basicity of propanoic acid($C_{2}H_{5}COOH$) is one.

Explanation:

• The basicity of an acid is estimated by the no. of $H^{+}$ ions it can give when dissolved in $H_{2}O$(water).
• In other words the number of $H^{+}$ ions an acid give in aqueous medium.
• The formula of propanoic acid ⇒ $C_{2}H_{5}COO^{-}H^{+}$.
• The propanoic acid will give 1 $H^{+}$ ion in $H_{2}O$, so its basicity is one, 1.
