c). The traditional way of comparing reactions is by the percentage yields. However, percentage yield takes no account of by-products. In order to decide which chemical process is greener, chemists have tried to develop ways of measuring 'greenness'. One of the most common methods is the atom economy. Calculate the atom economy of the following reactions: (i). CH2 Ph;P-CH2. + Ph P=0 (ii). он 200 °C (iii). CI CI .cI CI- CI NaOH CI
