4.Chemical Bonding and Molecular Structure
hard
Although $CN^-$ ion and $N_2$ molecule are isoelectronic, yet $N_2$ molecule is chemically inert because of
A
presence of more number of electrons in bonding orbitals
B
lone bond energy
C
absence of bond polarity
D
uneven electron distribution
(AIEEE-2012)
Solution
In nitrogen molecule, both the nitrogen atoms have same electronegativity. So it has zero polarity and hence less tendency to break away and form ions.
