Question

which of the following has higher melting point ?
a) formic acid b) acetic acid
c) propanoic acid d) butanoic acid​

Answer 1

Answer:

please mark me brainlist

Explanation:

acetic acid

Answer 2

The highest melting point is of d) butanoic acid.

• All are examples of carboxylic acid.
• In carboxylic acid hydrogen bonding is present this is because they have high melting and boiling points.
• Melting and boiling point increases with an increase in several carbon atoms in the principal chain or an increase in molecular weight.
• The melting point is highest for botanic acid as it contains 4 carbon atoms including a carboxylic carbon atom and the formula is CH3CH2CH2COOH.
• The least melting point is of formic acid as it contains only 1 carbon atom of carboxylic acid and the formula is HCOOH.
