5°C‚ respectively. The literature melting point of acetaminophen is 169.5 – 171.0°C‚ indicating that our final product was pure. Introduction The synthesis of acetaminophen involves the attraction of the electrophilic carbonyl group of acetic anhydride to the nucleophilic NH2 of the p-aminophenol. This occurs because the NH2 group is a better nucleophile than the OH group attached on the opposite side of the p-aminophenol. A new nitrogen-carbon bond is formed‚ producing

Molecule Assignment Parmvir Deo The molecule that I chose was creatine Creatine’s organic role cannot be disparaged. It assumes a key biological role for mammals‚ fish‚ reptiles and amphibians. Creatine helps muscles in delivering adenosine triphosphate (ATP)‚ the substance that facilitates blasts of energy down to the cellular level. Creatine is put away in muscle cells as phosphocreatine and is utilized to produce cell vitality for muscle compressions. The phosphate of ATP is exchanged to creatine

hold a specific type of functional group. Functional groups in different biological molecules play a significant role in the bio-molecules formation such as protein‚ DNA‚ sugars‚ amino acids‚ lipids and carbohydrates. Functional groups include the carbonyl‚ methyl‚ hydroxyl‚ amino‚ phosphate‚ and sulfhydryl. These are frequently found in atomic groups that covalently bond to the carbon in most organic molecules. The distinctive functional groups existent on a biological molecule determine the physical

COrdination compounds Question 9.1: Explain the bonding in coordination compounds in terms of Werner’s postulates. =Werner’s postulates explain the bonding in coordination compounds as follows: (i) A metal exhibits two types of valencies namely‚ primary and secondary valencies. Primary valencies are satisfied by negative ions while secondary valencies are satisfied by both negative and neutral ions. (In modern terminology‚ the primary valency corresponds to the oxidation number of the metal
