Which of the following statement is wrong?

Option: 1

A sigma bond is weaker than a \pi bond


Option: 2

Bond energies of \sigma and \pi bonds are of the order of more than 80 and approximately 65
\mathrm{kcal\, mol^{-1}}


Option: 3

Shape of a molecule is decided by the \sigma bond but not by \pi bonds


Option: 4

A \sigma - bond determines the direction between C- atoms but a \pi- bond has no primary effect which leads to bonding

As we have learnt,

Extent of overlapping is more when there is formation of \sigma bond which means it is a stronger bond having high bond energy than \pi bond. The shape of a molecule is decided by the \sigma bond but not the \pi bond.

Hence, option number (1) is correct.
