Following is an outline of a synthesis of the bronchodilator carbuterol, a beta-2 adrenergic blocker with high selectivity for airway smooth muscle receptors. Q.Suggest a structural relationship between carbuterol and ephedrine

The compound acetophenone has a very similar molar mass to that of benzoic acid and benzamide. However, acetophenone has a much lower m.p. (20 °C) than both such that, by contrast, it is a liquid at room temperature. By considering intermolecular forces and comparing functional group structure, account for this big difference in physical properties.
