[structure: A +

\mathrm{CH_3CH_2OH}

\longrightarrow

benzene ring]

\xrightarrow[\text{(iii) HCl}]{\text{(i) } \mathrm{H_2SO_4}\text{ (oleum), }\Delta\ \text{(ii) NaOH}}

B Consider the above reaction sequence. Identify the component A and component B :

The figure, in words

Reaction scheme with benzene ring drawn as the product of A + CH3CH2OH; options pair a formula with a drawn substituted benzene ring.

(1)A= $\mathrm{C_6H_5NH_2}$ ; B = [benzene ring bearing Cl]
(2)A = $\mathrm{C_6H_5N_2^{+}Cl^{-}}$ ; B = [benzene ring bearing OH]Official answer
(3)A = [benzene ring bearing Cl] ; B = $\mathrm{C_6H_5NH_2}$
(4)A = [benzene ring bearing OH] ; B = $\mathrm{C_6H_5N_2^{+}Cl^{-}}$
