deduce the number of carbon atoms, n, in a compound using the \([M + 1]^+\) peak and the formula \(n = rac{100 imes ext{abundance of } [M + 1]^+ ext{ion}}{1.1 imes ext{abundance of } M^+ ext{ion}}\)

interpret and use the general, structural, displayed and skeletal formulas of the classes of compound stated in the table on pages 29 and 30
