Question

How many of the following product(s) is/are same

i) Benzoic acid (COOH on benzene ring) treated with (i) Li/liq.NH3, (ii) NaOH, CaO, Δ, (iii) H2/Ni → P

ii) Cyclopentanone treated with (i) ∃CN-/HCN, (ii) LiAlH4, (iii) NaNO2/HCl, (iv) Zn-Hg/HCl → Q

iii) Cyclohexanone treated with (i) H2O2/BF3, (ii) CH3MgBr, (iii) Weak acid, (iv) PCC, (v) NaOH(room temp.) → Y, then Y treated with (i) PCC → R, or (ii) 1,2-ethanedithiol/HCl(g) followed by H2/Raney Ni, or (i) Zn-Hg/HCl, (ii) LiAlH4 → S
