How Z double bonds introduce kinks in the long hydrocarbon chain, decreasing the ability of the fatty acid to pack well in a crystalline lattice ?
explain further why this statement is true
"A saturated fatty acid sample has a high boiling point. A triacylglycerol is composed of glycerol and three saturated fatty acids. Therefore, a sample not containing this triacylglycerol will have a low boiling point."
Which of the following statements is incorrect?
A. Because like dissolves like, the nonpolar end of the soap molecule can dissolve greasy dirt, and the polar or ionic end of the molecule is attracted by water molecules.
B. By saturating the soap solution with NaCl or KCl, the saturation products of the Na+ and K+ salts of fatty acids are exceeded and most of the soap is precipitated, while glycerin dissolves in water.
The alkalinity provided by C. HO- damages the leather, making it difficult to remove dirt.D. Soaps are divided into two as hard and soft according to their consistency. Saturated and single-double-bonded fatty acids are used in hard soap making. Mild soap is obtained from fatty acids containing two or three double bonds.
