Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

i. pi bonding - because here colletral overlapping takes place ii. bonding because orbital overlap in same phase

orbital overlap in same phase means

wait..

explain briefly. plz sir
![eduncle-logo-app]()
in what condition antibonding form
![eduncle-logo-app]()
Two same-sign orbitals have a constructive overlap forming a molecular orbital with the bulk of the electron density located between the two nuclei. This molecular orbital is called the bonding orbital and its energy is lower than that of the original atomic orbitals. A bond involving molecular orbitals that are symmetric with respect to rotation around the bond axis is called a sigma bond (σ-bond). If the phase changes, the bond becomes a pi bond (π-bond). Symmetry labels are further defined by whether the orbital maintains its original character after an inversion about its center; if it does, it is defined gerade (g), German for “straight.” If the orbital does not maintain its original character, it is ungerade (u), German for “odd.”
