Hey Mate ..!!! ✋
➡ Here is ur answer:
▶ Fatty acids with doubles bonds to have a lower melting point than those with single bonds.
Explanation:
▶Single bonds in saturated fats mean that the fatty acid chain is straight, which allows the molecules to pack closely together to form a solid at room temperature (e.g. butter).
▶Double bonds in unsaturated fats cause kinks in fatty acid chain which prevent the molecules from packing closely together to form a solid at room temperature, so such fats are liquid in room temperature (e.g. olive oil).
▶Olive oil has a lower melting point than butter.
[Lower temperature required to turn olive into liquid, higher temperature required to turn butter into liquid]
▶Thus double bonding in unsaturated fats (olive oil) cause fatty acids to have lower melting point as compared to single bonding in saturated fats (butter).
Hope it helps..!!! ☺☺☺

The presence of double bond affect the melting point in fatty acids:
- Fatty acids with double bond have lower melting point in comparison to the fatty acids with single bonds. Literally, the arrangement of molecules in fatty acids with double bonds is unsaturated and complicated as well.
- This causes the molecules to remain loosely packed and hence they are present in liquid form at room temperature (such as olive oil).
- The arrangement of molecules in double bonded fatty acids is also irregular, not in a linear position like the single bonded fatty acids, that favours the lower melting point.
