Given below are two statements : Statement (I) :...
Given below are two statements :
Statement (I) : 1,2,3-Trihydroxypropane can be separated from water by simple distillation.
Statement (II) : An azeotropic mixture cannot be separated by fractional distillation.
In the light of the above statements, choose the correct answer from the options given below :
Statement (I) : 1,2,3-Trihydroxypropane can be separated from water by simple distillation.
Statement (II) : An azeotropic mixture cannot be separated by fractional distillation.
In the light of the above statements, choose the correct answer from the options given below :
Options
- ABoth Statement I and Statement II are true
- BBoth Statement I and Statement II are false
- CStatement I is true but Statement II is false
- DStatement I is false but Statement II is true
Correct answer
D. Statement I is false but Statement II is true
Step-by-step solution
Statement I: -Trihydroxypropane (glycerol) has a very high boiling point (around ) and it decomposes at its boiling point under normal atmospheric pressure. Therefore, it cannot be separated from water by simple distillation. Instead, it is separated by distillation under reduced pressure (vacuum distillation). Hence, Statement I is false.
Statement II: An azeotropic mixture is a constant boiling mixture in which the liquid and vapour phases have the exact same composition. Because there is no change in composition upon boiling, the components of an azeotropic mixture cannot be separated by fractional distillation. Hence, Statement II is true.
Therefore, Statement I is false but Statement II is true.
Answer: Statement I is false but Statement II is true
Statement II: An azeotropic mixture is a constant boiling mixture in which the liquid and vapour phases have the exact same composition. Because there is no change in composition upon boiling, the components of an azeotropic mixture cannot be separated by fractional distillation. Hence, Statement II is true.
Therefore, Statement I is false but Statement II is true.
Answer: Statement I is false but Statement II is true
