W, X, Y and Z are isomers of one another with molecular formula $\text{C}_8\text{H}_7\text{ClO}$. Each of the four isomers includes a benzene ring. Just one of the isomers has a chiral centre. The outcomes of six tests on W, X, Y and Z are listed in the table.
(a)[5]
Use the experimental data in the table above to work out which group(s), apart from the benzene ring, are present in the four isomers W, X, Y and Z.
Fill in the table below by identifying the group(s) found in each isomer.
(b(i))[4]
W, X, Y and Z all share the molecular formula $\text{C}_8\text{H}_7\text{ClO}$. Using the information in (a), suggest a structure for each isomer and draw them in the boxes.
(b(ii))[1]
Circle the chiral centre in one of the structures above.
