( (b) Compounds X and Y react in the presence of a small amount of NaOH to give compound Z, as shown in Scheme 1. NaOH + H2O OE od bach without solvent OEI OE OE Z х Scheme 1 (i) Given that the relative molecular masses for compounds X and Y are 132.0 gmol' and 194.0 g moll respectively. Calculate the percentage atom economy of the reaction. (Note: Relative atomic masses: C = 12.01 g mol-, H = 1.0 g moi", o = 16.0 g moll) (3 marks) In a typical experiment, 3.35 g of compound X and 4.18 g of compound Y yielded 5.48 g of compound Z. Calculate the percentage yield of compound Z. (3 marks) Give FOUR reasons why this reaction is considered as an example of green chemistry. (4 marks) (iii)
