Answer for question 2:

i. CH₃CH₂I + H₂ (Pd as catalyst) → CH₃-CH₃

ii. 2CH₃I + 2Na → CH₃-CH₃ (ethane)

iii. CH₂=CH₂ + H₂O → CH₃CH₂OH (ethanol)

iv. 2CH₂=CH₂ + SCl₂ →   ClCH₂-CH₂-S-CH₂-CH₂Cl (mustard gas)

Answer for question 3

i. CH₃CH₂OH + H₂SO₄ (in 443 K) →  CH₂=CH₂

ii.  ClCH₂-CH₂Cl + KOH + NaNH₂ → CH≡CH + DIBAL-H → CH₂=CH₂

Answer to question 4:

i.  CH₂=CH₂ + H₂/Pd → CH₃CH₃ + Cl₂ (CS₂ as solvent) →  ClCH₂-CH₂Cl (1, 2 dichloroethane)

ii.  CH₂=CH₂ + H₂/Pd → CH₃CH₃ + Cl₂ (CS₂ as solvent) →  ClCH₂-CH₂Cl + H₂O → HO-CH₂CH₂-OH (ethelene glycol)
