JEE Mains · Chemistry · STD 11 - 8.3. Organic chemistry purification and characterization
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 :
- A Both Statement I and Statement II are true
- B Both Statement I and Statement II are false
- C Statement I is true but Statement II is false
- D Statement I is false but Statement II is true
Answer & Solution
Correct Answer
(D) Statement I is false but Statement II is true
Step-by-step Solution
Detailed explanation
Statement I: \(1,2,3\)-Trihydroxypropane (glycerol) has a very high boiling point (around \(290^{\circ}\text{C}\)) and it decomposes at its boiling point under normal atmospheric pressure. Therefore, it cannot be separated from water by simple distillation. Instead, it is…
