Which among the following compounds has the highest freezing point of its 1 molal aqueous solution?
- A \(\mathrm{CF}_3 \mathrm{COOH}\)
- B \(\mathrm{CCl}_3 \mathrm{COOH}\)
- C \(\mathrm{CH}_3 \mathrm{COOH}\)
- D \(\mathrm{Cl}_2 \mathrm{CHCOOH}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{CH}_3 \mathrm{COOH}\)
Step-by-step Solution
Detailed explanation
The freezing point depression is given by \(\Delta T_f = i \times K_f \times m\). Since the molality \(m\) and the cryoscopic constant \(K_f\) are the same for all solutions, the freezing point depends on the van't Hoff factor \(i\). A higher freezing point corresponds to a…
