Options
- A( A )-( I ),( B )-( II ),( C )-( III ),( D )-( IV )
- B( A )-( I ),( B )-( III ),( C )-( II ),( D )-( IV )
- C( A )-( III ),( B )-( IV ),( C )-( II ),( D )-( I )
- D( A )-( IV ),( B )-( II ),( C )-( I ),( D )-( III )
Correct answer
C. ( A )-( III ),( B )-( IV ),( C )-( II ),( D )-( I )
Step-by-step solution
- Chloroform (b.p. 334 ~K ) and aniline (b.p. 457) are easily separated by the technique of distillation as both the liquids having sufficient difference in their boiling points. - The fractions of crude oil in petroleum industry is separated using fractional distillation due to less difference in boiling points of liquids. - Glycerol can be separated from spent-dye using distillation under reduced pressure. - Aniline is separated by steam distillation from aniline-water mixture.
