A) \[N{{O}_{2}}^{-}\]and\[N{{O}_{3}}^{-}\]
B) \[N{{H}_{4}}^{+}\]and\[N{{O}_{3}}^{-}\]
C) \[SC{{N}^{-}}\] and \[N{{H}_{2}}^{-}\]
D) \[N{{O}_{2}}^{-}\]and\[N{{H}_{2}}^{-}\]
Correct Answer: A
Solution :
[a] Hybridisation\[=\frac{1}{2}\] [No. of valence electrons of central atom\[+\] no. of monovalent atoms attached to it \[+.\] Negative charge if any \[-\] positive charge if any] \[N{{O}_{2}}^{-}\,\,H=\frac{1}{2}[5+0+1-0]=3=s{{p}^{2}}\] \[N{{O}_{3}}^{-}\,\,H=\frac{1}{2}[5+0+1-0]=3=s{{p}^{2}}\] \[N{{H}_{2}}^{-}\,\,H=\frac{1}{2}[5+2+1+0]=4=s{{p}^{3}}\] \[N{{H}_{4}}^{+},\,\,H=\frac{1}{2}[5+4+0-1]=4=s{{p}^{3}}\] i.e., \[N{{O}_{2}}^{-}\] and \[N{{O}_{3}}^{-}\] have same hybridisation.You need to login to perform this action.
