Chemical Bonding - Result Question 127
####27. The cyanide ion $CN^{-}$and $N _2$ are isoelectronic, but in contrast to $CN^{-}, N _2$ is chemically inert because of
(1997 C, 1M)
(a) low bond energy
(b) absence of bond polarity
(c) unsymmetrical electron distribution
(d) presence of more number of electron in bonding orbitals
Show Answer
Solution:
- $N _2$ is a neutral, non-polar, inert molecule while $CN^{-}$is a highly polar, highly active ion.
