Match the following if the molecular weights of X, Y and Z are the same : {:("Solvent","Boiling point","K"_(b)),(X,100^(@)C,0.68),(Y,27^(@)C,0.53),(Z,253^(@)C,0.98):}

Answer»

Solution :Higher BOILING POINT of a liquid means greater polarity and greater the polarity, higher is the VALUE for `K_(b)`. Hence, the CORRECTLY mathced values will be
`{:("Solvent","Boiling point","K"_(b)),(X,100^(@)C,0.68),(Y,27^(@)C,0.53),(Z,253^(@)C,0.98):}`
