Which orbital's are equivalent in homonuclear molecule?

1.	Which orbital's are equivalent in homonuclear molecule?
Answer» `sigma_(1S) and sigma_(2s)` `pi_(2PX) and pi_(2py)` `pi_(2px) and sigma_(2pz)` `sigma_(2px) and sigma_(2pz)^()` Solution :`pi_(2px) and pi_(2py)` Order of energy in molecular orbital : `sigma_(1s) lt sigma_(1s)^() lt sigma_(2s) lt sigma_(2s)^() lt sigma_(2p_(Z)) lt pi_(2p_(x)) = pi_(2p_(y))lt sigma_(2pz) lt pi_(2p_(x))^() = pi_(2p_(y))^() lt sigma_(2p_(z))^()`
