Question

The melting point of fatty acids depends upon chain length and _________

(a) The shape of the fatty acids

(b) The position of the double bond

(c) Charge on the carbon

(d) Degree of unsaturation

I have been asked this question in my homework.

This interesting question is from Lipid in section Biomolecules and Catalysis of Life Sciences

Answer 1

Correct option is (d) Degree of unsaturation

For explanation I would say: The melting point of fatty acids is determined by the length of the chain and number of the double bond. The longer the chain, the higher the melting point and the larger the number of double bonds the lesser the melting point.
