why hydrogen of COOH group is removed in the preparation of methyl salicylate from salicylic acid in the presence of sulphuric acid
EsterificationSince the salicylic acid is acid, so it will be reacting with ethanol to form ester The two-part name of an ester: the name of the hyrocarbon group from the alcohol comes first, then the name of the carboxylate group derived from the acid name by replacing "-ic" with "-ate"Therefore the name will be ethyl salicylate C9H10O4 (google it to get the image)
Salicylic acid contains carbon, hydrogen, and oxygen.
Phenyl salicylate is a very polar molecule. It has strong intermolecular hydrogen bonds, hydrogen bonded to oxygen I concur!! The hydroxyl (-OH) group that is on the salicylic acid part of the molecule allows strong hydrogen bonding to occur. It's lack of solubility in water though could be the result of a stronger attraction to itself than to being solvated by water.
Sulphuric acid is H2SO4 Sodium hydrogen carbonate is NaHCO3
Sulphuric acid is composed of the elements sulfur, oxygen, and hydrogen. Its chemical formula is H2SO4.
The systematic name for sulphuric acid is sulfuric acid.
Sulfa, hydrogen, & oxygen.
Fe(NO3)3 + 3 C6H4(OH)COOH → Fe(C6H4(OH)COO)3 + 3 HNO3
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
It is slightly basic. Behaves almost completely neutral.
When copper reacts with sulphuric acid, copper sulfate is formed. This reaction involves the displacement of hydrogen in sulphuric acid by copper, resulting in the formation of copper sulfate and hydrogen gas.
Lead is not reactive enough to displace hydrogen from dilute HCl or dilute sulfuric acid. The reduction potential of lead is lower than that of hydrogen, so it cannot effectively displace hydrogen in these reactions. Other metals like zinc or aluminum are used instead due to their higher reactivity and ability to displace hydrogen.
