25. The highest occupied molecular orbital in HF is
A. bonding
B. antibonding
O C. non-bonding
O D. ionic
Answers
Answer:
The HOMO orbital is the highest energy molecular orbital occupied by electrons. In HF, the HOMO orbitals are the double degenerate pi 2px and 2py and pi orbitals
Answer:
The highest occupied molecular orbital in HF is bonding.
Explanation:
In chemistry, a molecular orbital is a mathematical function describing the location and wave-like behavior of an electron in a molecule. This function can be used to calculate chemical and physical properties such as the probability of finding an electron in any specific region. The terms atomic orbital and molecular orbital were introduced by Robert S. Mulliken in 1932 to mean one-electron orbital wave functions. At an elementary level, they are used to describe the region of space in which a function has a significant amplitude.
In an isolated atom, the orbital electrons' location is determined by functions called atomic orbitals. When multiple atoms combine chemically into a molecule, the electrons' locations are determined by the molecule as a whole, so the atomic orbitals combine to form molecular orbitals. The electrons from the constituent atoms occupy the molecular orbitals. Mathematically, molecular orbitals are an approximate solution to the Schrödinger equation for the electrons in the field of the molecule's atomic nuclei.
