Answers
Answer:
bond order increase
hope it's help you
According to the above-given options, the one which is not possible due to back bonding is
(1). State of hybridization may change
Back bonding affects all other three terms given in options I.e. bond order, bond angle, and lewis acidic strength.
But the state of hybridization is not affected always. It depends on whether it changes or not.
Justification :
- Back bonding is chemical bonding between an atom of a compound with a single electron and the other with a vacant or an empty orbital.
Option a: correct
The state of hybridization of the central atom does not necessarily change for every back bonding. It might also remain unchanged.
Option b:
Back bonding leads to a decrease of bond length as it forms a pi-bond and allows the molecule to complete its octet. This increases the bond order.
Option c:
Back bonding increases electron density which leads to an increase in bond angle.
Option d:
When back bonding takes place, the shortage of electrons is managed, and thus the lewis acidic character strength decreases.
