Correct answer
DStatement I is false but Statement II is true
Step-by-step explanation
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
