CsBr3 contains:
Correct answer: C. Cs+ and Br3- ions
- A. Cs-Br covalent bonds
- B. Cs3+ and Br- ions
- C. Cs+ and Br3- ions
- D. Cs3+ and Br33- ion
Explanation
CsBr3 is an ionic compound. Cs is a monovalent ion, i.e., Cs+. So, the other ion will be Br3−. Therefore, the correct answer is Cs+ and Br3− ions. Option A is incorrect as it implies covalent bonds in an ionic compound. Option B is incorrect as Cs does not have a 3+ charge. Option D is incorrect as Cs does not have a 3+ charge and Br does not have a 3− charge.
