Problem- In terms of Hucket theory, determine orbital energies and molecular orbitals of a) butadiene and b) cumulene. Hint: Even though, the cumulene has three carbons, treat as 4 basis p orbitals. visibly, construction of determinant is the key
I am not able to get the correct answer please help me
