Question:
Which of the following has the lowest melting point?
Which of the following has the lowest melting point?
Show Hint
Fatty acids with cis double bonds are typically liquid at room temperature, while those with trans double bonds or no double bonds are usually solid.
Updated On: May 5, 2025
- Fatty acids with sites of unsaturation with \(\text{cis}\) double bonds
- Fatty acids with sites of unsaturation with \(\text{trans}\) double bonds
- Fatty acids with no sites of unsaturation
- Fatty acids with longer hydrophobic tails
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Fatty acids with \(\text{cis}\) double bonds have kinks in their structures that prevent tight packing, leading to lower melting points. In contrast, trans double bonds or saturated fatty acids pack more tightly and have higher melting points.
