Which of the following orderof energies of molecular orbitals of `N_(2)` is correct?

Options

A. `(pi2p_(y) lt (pi2p_(z))lt(pi2p_(x))=(pi2p_(y))`
B. `(pi2p_(y))gt(pi2p_(z))gt(pi2p_(x))=(pi2p_(y))`
C. `(pi2p_(y))lt(pi2p_(z)) lt(pi2p_(x))=(pi2p_(y))`
D. `(pi2p_(y))gt(pi2p_(z))lt(pi2p_(x))=(pi2p_(y))`

Answer

A

Explanation

a) The correct increasing order of energies of molecular orbitals of `N_(2)` is given below `pi` is `ltpi^(star)1sltpi2sltpi^(star)2slt(pi2p_(x) = pi2p_(y))lt pi2p_(z)lt(pi^(star)p_(x)=pi^(star)2p_(y))ltpi^(star)2p_(z)`
