Is stearic acid polar or non-polar?
Stearic acid, a naturally-occurring fatty acid with chemical formula C18H36O2 consists of a polar carboxylic acid region at one end of the molecule, with a long non-polar hydrocarbon tail.
What kind of bond is stearic acid?
saturated fatty acid
Stearic acid is a fatty acid composed of 17 carbons in a linear chain plus a carboxylic acid group. It is bonded to as many hydrogen atoms as possible, so it is said to be a saturated fatty acid. Stearic acid may be obtained from many animal and vegetable fats and oils.
Why does stearic acid not dissolve in water?
Stearic acid has the following structure: While the carboxylic group makes stearic acid soluble in water due to the potential hydrogen bonding and its polar character, the long hydrocarbon chain is hydrophobic and repels the water molecules to the extent that the compound is insoluble in water.
Is stearic acid hydrophobic or hydrophilic?
The long alkane “tail,” CH3 (CH2)16-, is hydrophobic. Stearic acid and water are probably miscible. Stearic acid would probably dissolve in nonpolar solvents such as hexane, C6H14. Stearic acid contains hydrophilic and hydrophobic regions.
What is stearic acid soluble in?
Stearic acid is a saturated fatty acid that can deposit on the surface in special conditions. This acid is insoluble in water and soluble in ethanol.
Which chemical from the list are non polar?
Any of the homonuclear diatomic elements: H2, N2, O2, Cl2 (These are truly nonpolar molecules.) Carbon dioxide – CO. Boron trifluoride – BF. Benzene – C6H.
Why is stearic acid nonpolar?
Consider stearic acid, a type of lipid known as a fatty acid. It has an 18 C atom chain with a carboxylic acid group (RCO2H) at one end. The carboxyl end (shown in red) containing the two oxygens is polar, but the rest of the molecule is completely nonpolar.
