Sticky Note
Which of the following is the most stable compound? Methyne ,Benzene , Cis-Methyne ,Trans-Methyne
  1. Methyne
  2. Benzene
  3. Cis-Methyne
  4. Trans-Methyne
Explanation

Benzene is the most stable compound among "Methyne", "Benzene", "Cis-Methyne", and "Trans-Methyne". 


Benzene:

Due to its aromatic nature with delocalized π electrons, benzene exhibits significantly higher stability compared to other compounds like alkenes. 

Trans-Methyne:

While more stable than cis-methyne, trans-methyne is still less stable than benzene because it lacks the extended conjugation of the aromatic ring. 

Cis-Methyne:

This compound has the least stability due to steric hindrance between the substituents on the same side of the double bond. 

Methyne:

This term refers to a single carbon atom with three hydrogen atoms attached, which is not a stable compound on its own.
