Here are the essential concepts you must grasp in order to answer the question correctly.
Molecular Orbitals
Molecular orbitals (MOs) are formed by the combination of atomic orbitals when atoms bond together. They can be classified as bonding, antibonding, or non-bonding orbitals, which influence the stability and reactivity of the molecule. Understanding MOs is crucial for predicting the electronic structure and properties of molecules, including their geometry and energy levels.

But-3-en-2-one Structure
But-3-en-2-one, also known as mesityl oxide, is a four-carbon compound with a double bond and a ketone functional group. Its structure includes a carbon-carbon double bond between the second and third carbons and a carbonyl group (C=O) at the second carbon. Recognizing the arrangement of these functional groups is essential for accurately drawing its molecular orbital diagram.

Hybridization
Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate bonding in molecules. In but-3-en-2-one, the carbon atoms involved in the double bond and the carbonyl group exhibit sp2 hybridization, which influences the geometry and bond angles. Understanding hybridization helps in visualizing the molecular structure and predicting the behavior of electrons in molecular orbitals.
