Choose the incorrect formula out of the four compounds for an element \(X\) below
- A \(X_2O_3\)
- B \(X_2Cl_3\)
- C \(X_2(SO_4)_3\)
- D \(XPO_4\)
Answer & Solution
Correct Answer
(B) \(X_2Cl_3\)
Step-by-step Solution
Detailed explanation
\(X_2O_3\Rightarrow X^{3+}O^{2-}\) \(X_2Cl_3\Rightarrow X^{3+}Cl^{2-}\) \(X_2(SO_4)_3\Rightarrow X^{3+}SO_4^{2-}\) \(XPO_4\Rightarrow X^{3+}PO_4^{3-}\) Because \(Cl^{2-}\) does not exist. So, \(X_2Cl_3\) is incorrect. The correct formula should be \(XCl_3\).
