Question

Greater the number of carbon atoms in a chain of fatty acid



a.Greater will be the boilung point ,ð lesser will be boiling point,c)lesser will be melting point.

Answer 1

greater the no.of carbon atoms in a chain of fatty acid greater will be the boiling point.

Answer 2

Answer:

The correct answer is a. Greater will be the boiling point.

Explanation:

Relationship of carbon chain length and boiling point:

• As the number of Carbon atoms increases, the van der Waal's force increases and the boiling point increases.
• Due to this, first four members of alkane family are gases, pentane to heptadecane are liquids and higher alkanes are solids.

Relationship of carbon chain length and melting point:

• The melting point of a fatty acid chain increases as the number of carbons in the chain grows.
• At room temperature, shorter chain fatty acids are more likely to be liquid, while longer chain fatty acids are more likely to be solid.
