LCAO is short for linear combination of atomic orbitals and implies that we can take two atomic orbitals ϕ 1, ϕ 2 and create two molecular orbitals ψ 1, ψ 2 from them by linear combination: ψ 1 = a 1 ϕ 1 + b 1 ϕ 2 and ψ 2 = a 2 ϕ 1 + b 2 ϕ 2.

"WebA cyclohexane molecule can take up any conformations. The synthesis and structure of cyclohexane are a very important type of prototype because of a wide range of compounds. The internal angles for a hexagon are found to be 120°. But the angle between every bond of a carbon chain is found to be 109.5° that makes it a tetrahedral angle.
