The highest energy occupied molecular orbital in the C-C bond of the C2 molecule is?
Butoxors [25]

The highest energy occupied molecular orbital in the C-C bond of the C₂ molecule is 2pπ orbitals.

<h3>What is Molecular Orbital Theory?</h3>

According to this theory,

  • Molecular orbitals are formed by intermixing of atomic orbitals of two or more atoms having comparable energies
  • The number of molecular orbitals formed is equal to the number of atomic orbitals combined.
  • The shape of molecular orbitals formed depends on the type of atomic orbitals combined
  • Only atomic orbitals having comparable energies and the same orientation can intermix
  • Bonding M.O. is formed by the additive effect of atomic orbitals and thus, has lower energy and high stability.
  • Antibonding M.O. is formed by the subtractive effect of atomic orbitals and thus, has higher energy and low stability.
  • Bonding M.O. is represented by \sigma, \pi, \delta while Antibonding M.O. is represented by \sigma^*, \pi^*, \delta^*\\

In a certain time, light travels 4.96 km in a vacuum. during the same time, light travels only 3.36 km in a liquid. what is the
Natali5045456 [20]

the refractive index of the liquid is 1.476

The refractive index, which has no dimensions, measures how quickly light passes through a substance.

It can also be described as the difference between the speed of light in a vacuum and a medium.

Refractive index is equal to the product of the light's liquid and vacuum speeds.

Therefore.

speed of light in vacuum = 4.96 km/t

speed of light in liquid = 3.36 km/t

Refractive index = 4.96/3.36

Refractive index =1.476

Therefore, the refractive index of the liquid is 1.476
