AIIMS 2019 Chemistry Hybridization MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Assertion: I2O5\text{I}_2\text{O}_5 is used to detect CO\text{CO}

Reason: In I2O5\text{I}_2\text{O}_5, the oxidation number of I is 5.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Correct Answer

Option B

Detailed Explanation

Cyanogen gas, with the molecular formula (CN)₂, exhibits sp hybridization due to the triple bond between the carbon and nitrogen atoms, resulting in a linear molecular geometry. This linearity and the presence of a triple bond contribute to its unique properties, which are somewhat similar to those of halogens, particularly in terms of reactivity. The other options are not relevant as they do not provide any additional information or context regarding the structure or properties of cyanogen gas. Understanding the hybridization and geometry helps clarify the behavior of cyanogen in chemical reactions.
