In the molecular orbital model of cyclobutadiene, how many -antibonding molecular orbitals are there?
1 answer:
There are one antibonding molecular orbitals present in molecular orbital model of c.
The cyclobutadiene has a pi system comprised of four individual atomic p - orbital and thus should have a four pi molecular orbitals. The compound is the prototypical antiaromatic hydrocarbon with 4 - electrons . Its rectangular structure is the result of jahn teller reaction which disorder the molecule and lowers its symmetry , converting the triplet to a singlet ground state. It is a small annulene . The delocalisation energy of the
electrons of the cyclobutene is predicted to be zero .

<u>Answer:</u> The volume of solution required is 0.0275 L.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
Given mass of copper = 4.24 g
Molar mass of copper = 63.55 g/mol
Putting values in above equation, we get:
The chemical equation for the reaction of potassium dichromate and copper follows:
By Stoichiometry of the reaction:
3 moles of copper reacts with 1 mole of potassium dichromate.
So, 0.067 moles of copper will react with = of potassium dichromate
To calculate the volume of potassium dichromate, we use the equation:
We are given:
Moles of potassium dichromate = 0.022 mol
Molarity of solution = 0.800 M
Putting values in above equation, we get:
Hence, the volume of solution required is 0.0275 L.
