Ethyl palmitate is an organic compound with the chemical formula C18H36O2. It is a colorless solid with a wax-like odor. Chemically, ethyl palmitate is the ethyl ester of palmitic acid.
Ethyl palmitate is used as a hair- and skin-conditioning agent.<span />
Oleic acid belongs to class of alkene and in alkenes, addition of across that is carbon carbon double bond results in the formation of alkane as a product in the presence of specific catalyst such as nickel, palladium and platinum. The reaction is said to be hydrogenation reaction.
Oleic acid () consist of 17 carbon atoms attached to 33 hydrogen atoms with one double bond between two carbon atoms and one carboxylic group i.e.(). When oleic acid is hydrogenated or reacts with hydrogen in the presence of catalyst, then the carbon carbon double breaks by the addition and alkane product i.e. stearic acid () is formed.
The chemical reaction is shown in the image.
It’s the 3d one
Good luckkkkkkkk
Ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .
Ethers will not have a hydrogen atom attached to the oxygen atom as alcohols do. Because ether molecules can not form intermolecular hydrogen bonds, their boiling points are much shorter than those of alcohol with such a comparable mass.
Owing to the combination of intermolecular H-bonding in alcohols though not in ethers, alcohols possess higher boiling temperatures than isomeric ethers.
Therefore, ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .
