Which has the highest freezing point:

Options

A. `1M` glucose
B. `1M NaCl`
C. `1M CaCl_(2)`
D. `1 M AIF_(3)`?

Explanation

To determine which solution has the highest freezing point among 1 molar glucose, 1 molar NaCl, 1 molar CaCl2, and 1 molar AlF3, we can use the concept of freezing point depression, which is described by the formula:

\[ \Delta T_f = i \cdot K_f \cdot m \]

Where:
- \(\Delta T_f\) is the depression in freezing point.
