MCQ
Among $i-iii$ the boiling point follows the order
  • ✓
    $(ii) < (i) < (iii)$
  • B
    $(iii) < (ii) < (i)$
  • C
    $(i) < (ii) < (iii)$
  • D
    $(ii) < (iii) < (i)$
✓

Answer

Correct option: A.
$(ii) < (i) < (iii)$
a
In $(III)$ intermolecular $H$ bonding takes place so its boiling point will be highest while in $(II)$ intramolecular $H$ bonding takes place. $ii \,<\, i\,<\, iii$
