EXPERIMENT 6 – Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical

that this reaction works very well Despite the ease of our reaction‚ a few comments are in order. Our alkyl halide‚ cinnamyl bromide‚ is extremely reactive. As an electrophile‚ it is activated by something called the phenacyl effect (Reeve J. Am. Chem. Soc. 1954‚ 76‚ 2280-2281). The phenacyl effect applies to halides that are adjacent to a _-bond‚ such as a simple double bond‚ an aromatic ring‚ or a carbonyl. The neighboring _-bond stabilizes both SN2 substition and SN1 ionization (Figure
