Question

Convert benzene into methane

Answer 1

Answer:

1. 0zonolysis of benzene to form 3 moles of glyoxal [(CHO)2]

2. catalytic hydrogenation (H2/Ni) of glyoxal to form ethane.

Now to convert the ethane into methane

CH3-CH3+ C12/light---- CH3-CH2-Cl

CH3-CH2-Cl + KOH (aq)-- CH3-CH2-OH

CH3-CH2-OH + K2Cr207/H2SO4----- CH3-COOH

CH3-COOH + NaOH------- CH3-COONa

CH3-COONa+ CaO + NaOH + heat ---------> CH4
