Reactivity The reactivity of a methylgroup depends on the adjacent substituents. Methyl groups can be quite unreactive. For example, in organic compounds, the methylgroup resists attack by even the strongest acid s. Oxidation The oxidation of a methylgroup occurs widely in nature and industry. The oxidation products derived from methyl are CH sub 2 sub OH, CHO, and CO sub 2 sub H. For example, permanganate often converts a methylgroup to a carboxyl COOH group, e.g. the conversion of toluene to benzoic acid .

It is a clear colorless liquid that is only slightly soluble in water, but very soluble in most organic solvents. Methyl phenylacetate has a strong odor similar to honey. The odor is so strong that recommended smelling is of a solution with 10 or less methyl phenylacetate. This compound also naturally occurs in brandy , capsicum , coffee , honey , black pepper pepper and some wine . Methyl phenylacetate is used in the flavor industry and in perfumes to impart honey scents. References Reflist Methyl Phenyl Acetate.
