question_answer 1)

  What will be the correct order of vapour pressure of water, acetone and ether at\[30{}^\circ C\]? Given that among these compounds, water has maximum boiling point and ether has minimum boiling point? (a) Water < ether < acetone                                       (b) Water < acetone < ether (c) Ether < acetone < water                                         (d) Acetone < ether < water

Answer:

  (b) Greater is the boiling point of a liquid, lesser will be its vapour pressure. Water < acetone < ether
