Which of the following statements are correct? A. \(F_2\) is less reactive than \(ClF\) B. \(F_2\) is more reactive than \(ClF\) C. \(F-F\) bond is weaker than \(Cl-F\) bond D. \(F-F\) bond is stronger than \(Cl-F\) bond Choose the correct answers from the options given below: |
A, B and C only B and D only B, C and D only B and C only |
B and D only |
The correct answer is option 2. B and D only B. Fluorine \((F_2)\) is more reactive than chlorine fluoride \((ClF)\): Fluorine is the most electronegative element, making it a very strong oxidizing agent. This means that it is more likely to gain electrons and form bonds with other elements. Chlorine fluoride, on the other hand, is a less reactive molecule because the chlorine atom is already in a negative oxidation state (-1). This makes it less likely to lose electrons and form bonds with other elements. D. The \(F-F\) bond is stronger than the \(Cl-F\) bond. The strength of a bond is determined by the amount of energy required to break it. The \(F-F\) bond has a bond dissociation energy of 159 kJ/mol, while the \(Cl-F\) bond has a bond dissociation energy of 254 kJ/mol. This means that the \(F-F\) bond is stronger than the \(Cl-F\) bond. Therefore, the correct answers are B and D only. |
