Step-by-step solution
I. Etard reaction: This reaction converts toluene into benzaldehyde using C. Chromyl chloride as the reagent. II. Hydroxylation: The hydroxylation of an alkene to a vicinal diol is a common reaction. A reagent used for this is cold, dilute, alkaline D. ( KMnO ₄ ) (Baeyer's reagent). III. Dehydrohalogenation: This is an elimination reaction where a hydrogen halide is removed from an alkyl halide to form an alkene. It typically requires a strong base like A. Alcoholic KOH. IV. Friedel-Crafts reaction: This is an elec
