Consider the catalytic hydrogenation of compounds P, Q and R as indicated in the table. The number of carbocyclic rings and π-bonds present in compounds P, Q and R have been indicated. Complete the table by identifying the missing positions described by notations W, X, Y and Z

1. (a) W = C₄₀H₈₂, X = C₁₀H₂₂, Y = 3 and Z = 1
2. (b) W = C₄₀H₈₀, X = C₁₀H₂₀, Y = 2 and Z = 2
3. (c) W = C₄₀H₇₆, X = C₁₀H₂₂, Y = 0 and Z = 4
4. (d) W = C₄₀H₇₈, X = C₁₀H₁₆, Y = 1 and Z = 3
