A reaction scheme is shown in Fig. 7.1. The reagents needed for reaction 2 and reaction 3 are stated. Reaction 5 takes place when $$\(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NH}_{2}\)$$ is mixed with compound $$\(\mathbf{V}\)$$. No special conditions are required. Fig. 7.1 Complete Table 7.1 by adding the reaction numbers, 1, 2, 3, 4, 5 and 6 , to the right-hand column. Use the reaction numbers given in Fig. 7.1. Each of the numbers 1, 2, 3, 4, 5 and 6 should be used once only. Table 7.1
