Concept explainers
a)
Interpretation:
Number of carbon-carbon sigma bonds present in the given benzene has to be identified.
Concept introduction:
Sigma bonds: A sigma bond is a covalent bond formed by head on overlap of atomic orbitals that carries two electrons. The bonding represented as a single line between two atoms.
Head-on overlap:
Head-on overlap of two atomic orbitals forms a molecular orbital known as sigma bonds.
Side-to-side overlap:
Side-to-side overlap of two atomic orbitals forms a molecular orbital known as pi-bonds.
b)
Interpretation:
Number of carbon-carbon sigma bonds present in the given cyclobutane has to be identified.
