Question

In Ethane molecule how many carbon orbitals are equivalent and degenerate in nature? a)3 b)6 c)4 d)5

Answer 1

Answer:

c) 4

Explanation:

Ethane molecule consists of two carbon atoms and six H-atoms (C2H6 ). p-orbitals (px, py, pz) undergo Sp3-hybridization to produce four Sp3-hybrid orbitals for each carbon atom.

Answer 2

Answer:

In Ethane molecule 4 carbon orbitals are equivalent and degenerate in nature

Explanation:

• Methane's valence molecular orbitals are delocalized across the entire nuclear skeleton, making it difficult to assign any one orbital to a specific C-H bond. It is possible to see how complex the orbital structure becomes as energy increases. Methane has four valence molecular orbitals (bonding), one with one nodal plane and three degenerate orbitals with one nodal plane.
• The ethane molecule has fourteen valence electrons that are distributed across seven bonding molecular orbitals. Four molecular orbitals exist as degenerate pairs. Ethane's molecular orbitals, like those of methane, exhibit increasing nodal structure as orbital energy increases.
