(a(ii))[4]
Complete the table with details of the mechanism in reaction 1.
(b)[1]

(c(i))[2]
Identify the reagents and conditions for converting cyclohexene into adipic acid (hexanedioic acid), $\text{HO}_2\text{C(CH}_2)_4\text{CO}_2\text{H}$.
(c(ii))[3]
Suggest three key differences between the infra-red spectra of cyclohexene and adipic acid. For each one, name the bond involved and its characteristic absorption range (in wavenumbers).
