Which of the following would result in the formation of strongest π- bond if the
molecular axis is x-axis ?
(A) 2px +2px
(B) 2p, +2py
(C) 2p, +3dy
(D) 2p2 +4p2​

Answer 1

Answer:

(A) 2px +2px result in the formation of strongest π- bond if the molecular axis is x-axis , because the density of electron in case of p-x orbital remain highest along the x-axis and when electron cloud of two similar orbital interacts with each other the π—bond become stronger due to similar energy profile/ level rather than matching of two different kind of orbital.

Answer 2

The Correct answer is Option (A)

Pi bonds are the covalent chemical bond in which two lobes of an orbital overlap with the two lobes of other orbitals.

Explanation:

The strongest π bonds are 2pₓ +2pₓ if the axis is the x-axis.

The density of electron of pₓ remains highest along x-axis.

When the electron cloud of two similar orbitals interacts with each other the pi bond becomes strong.

The answer is option (A)
