Match the entries of column I with appropriate entries of column II and choose the correct option out of the four options given.
| Column I | Column II |
| (a) CH4 + Cl2/hν → | (i) CH3—Cl + POCl3 + H2O |
| (b) H2C=CH2 + HCl → | (ii) CH3—I + NaBr |
| (c) CH3—OH + PCl5 → | (iii) CH3—Cl + HCl |
| (d) CH3—Br + NaI/Acetone → | (iv) CH3—CH2Cl |
Answer & explanation
Correct answer: option 2
Synthesis of Haloalkanes:
(a) From Alkanes: CH4 + Cl2/hν → CH3—Cl + HCl
(b) From Alkenes: H2C=CH2 + HCl → CH3—CH2Cl
(c) From Alcohols: CH3—OH + PCl5 → CH3—Cl + POCl3 + H2O
(d) From other halides: CH3—Br + NaI/Acetone → CH3—I + NaBr
