Anabolism is the process that the body utilizes. This is the energy released using catabolism to synthesize into complex molecules.
Acetophenone can be converted into 2-phenyl-2-butanol using a Grignard reagent. Using CH3MgI, the carbonyl group of acetophenone will be attacked by this reagent and yield the alcohol: 2-phenyl-2-propanol.
The rate of a reaction is calculated using the concentrations of reactants.
Grignard reagents react rapidly with water.
By using grignard reagent
Grignard reactions must be carried out in an anhydrous environment in an anhydrous solvent (e.g. anhydrous ether). Why? Grignard reagents behave essentially as a carbanion, and are extremely reactive. Therefore they cannot be carried out while acidic hydrogens, or other positive reactive centers are present (carbonyl compounds such as acetone) in the reaction mixture because there is no way to stop the Grignard from reacting with these other compounds rather than the desired reactant. If phenylmagnesium bromide were prepared, and ANY water was present in the reaction mixture phenylmagnesium bromide would not hesitate to react with water--stealing one of its hydrogens. This hydrogen would therefore replace the attached --MgBr to form benzene.
