Question

The below mentioned complex is not the type of inclusion compounds

• A. Channel‐Lattice type
• B. Quinhydrone complex
• C. Layer type
• D. Clathrates

Answer 1

The Correct Option is B

The given question is regarding inclusion compounds and which among the provided options is not a type of inclusion compound. To answer this, we need to understand what inclusion compounds are and then look at each option to identify the correct answer.

Inclusion compounds are chemical compounds where one chemical substance, the 'guest', is contained within the spatial structure of another substance, the 'host'. They are formed when the guest molecules are located in the cavity of the host molecules. Let's evaluate each option:

• Channel-Lattice Type: These compounds have a structure that forms channels through which guest molecules or atoms can pass and be held. Thus, they qualify as inclusion compounds.
• Layer Type: Such compounds consist of layers of host molecules between which guests are incorporated, making them a type of inclusion compound as well.
• Clathrates: These are classic examples of inclusion compounds where the guest molecule is trapped within the cage-like structure of the host without any specific chemical bonding, thereby categorizing them as inclusion compounds.
• Quinhydrone Complex: These compounds are formed from quinones and phenols, such as hydroquinone with quinone. The stabilization is through hydrogen bonding or π-π interactions rather than encapsulating or surrounding the guest in a host matrix.

Based on this analysis, the quinhydrone complex is not an inclusion compound as its formation is based on interaction through bonding rather than physical inclusion. Hence, this is the correct answer.

Therefore, the correct answer is the Quinhydrone complex.
