In each of the following question, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R). Choose the correct answer as:
Assertion (A): The O—O bond length in H2O2 is shorter than that of O2F2.
Reason (R): H2O2 is an ionic compound.
Answer & explanation
Correct answer: option 4
The correct answer is option 4. If both assertion and reason are false.
Assertion (A):The \(O—O\) bond length in \(H_2O_2\) is shorter than that of \(O_2F_2\).
This statement is false. In reality, the \(O—O\) bond length in \(H_2O_2\) (Hydrogen Peroxide) is longer than that in \(O_2F_2\) (dioxygen difluoride). This is because in \(H_2O_2\), the oxygen atoms are connected by a single covalent bond, which is longer than the \(O=O\) double bond in \(O_2F_2\).
2. Reason (R): \(H_2O_2\) is an ionic compound.
This statement is false as well. \(H_2O_2\) is not an ionic compound; it is a covalent compound. In \(H_2O_2\), the oxygen atoms are bonded together by a covalent bond, where they share electrons.
So, both the assertion and the reason provided are incorrect. The correct explanation is that \(H_2O_2\) is a covalent compound, and the \(O—O\) bond length in \(H_2O_2\) is longer than that of \(O_2F_2\). Thus, the correct option is "If both assertion and reason are false."
