For which of the following liquid mixtures _ mix H=0 and _ mix V=0 ?

Options

  1. AEthyl chloride, ethyl bromide
  2. BEthanol, acetone
  3. CPhenol, aniline
  4. DChloroform, acetone

Correct answer

A. Ethyl chloride, ethyl bromide

Step-by-step solution

( Ideal solutions, are possible if molecules of solute and solvent are almost of same size and have identical polarity and they should have almost same inter molecular attraction. For example, solutions of ethyl chloride and ethyl bromide almost behave as ideal solutions. The characteristics of ideal solution is that no heat should be evolved or absorbed during the mixing, i.e. H_ mix =0 and also no expansion or contraction on mixing, i.e. V_ mix =0
