Question

Arrange benzene, n-hexane and ethyne in decreasing order of acidic behaviour. Also give reason for this behaviour.

A group of students is analyzing the bonding in ethene (C₂H₄), ethyne (C₂H₂), and methane (CH₄) using the concept of hybridization. They discover: - In methane, carbon forms four sigma bonds using sp³ hybrid orbitals. - In ethene, carbon forms three sigma bonds using sp² hybrid orbitals, and a π bond using unhybridized p-orbitals. - In ethyne, carbon uses sp hybrid orbitals and forms two π bonds due to two unhybridized p-orbitals.

The hybridization of carbon in ethyne (C₂H₂) is:

Raj, a Class 11 student, is studying organic chemistry and learning how carbon compounds form different structures. He comes across three compounds in his chemistry lab: 1. Methane (CH₄) 2. Ethene (C₂H₄) 3. Ethyne (C₂H₂) He notices that all three compounds contain carbon and hydrogen, but their bonding and reactivity are different. He is curious to learn how their structures influence their properties.
