Q50 / 160 · JIPMER 2014 · Chemistry
Which of the following compounds has the lowest melting point?
- A$\mathrm{CaBr}_2$
- Correct answerB$\mathrm{Cal}_2$
- C$\mathrm{CaF}_2$
- D$\mathrm{CaCl}_2$
Solution
As covalent character increases, melting point decreases, thus order of melting point is $\mathrm{CaF}_2\gt\mathrm{CaCl}_2\gt\mathrm{CaBr}_2\gt\mathrm{Cal}_2$
Hence, the correct answer is option: 'B'.
