Question

Which of the following forms strong pπ - pπ bonding?

Options

• \[\ce{S8}\]

• \[\ce{Se6}\]

• \[\ce{Te4}\]

• \[\ce{O2}\]

Answer 1

\[\ce{O2}\]

Explanation:

\[\ce{O2}\] forms strong pπ - pπ bonding due to the small atomic size and high electronegativity of oxygen, which enable effective overlap of p-orbitals to form a double bond \[\ce{(O = O)}\]. In contrast, \[\ce{S8, Se6, Te4}\] have larger atomic sizes, making pπ - pπ bonding weak and ineffective.
