${\ddot{\mathrm{N}}}_{\mathrm{a}}$ :- Superlocalised ${\mathrm{L}}_{\mathrm{p}}/+\mathrm{M}$ of $-\stackrel{\oplus }{\mathrm{N}}\mathrm{H}$

${\ddot{\mathrm{N}}}_{\mathrm{b}}$ :- SIR effect localized ${\mathrm{l}}_{\mathrm{p}}$

${\ddot{\mathrm{N}}}_{\mathrm{c}}$ :- delocalised ${\mathrm{l}}_{\mathrm{p}}/-\mathrm{M}$ of $-C=O$

${\ddot{\mathrm{N}}}_d$ :- Delocalised lp & +I of $2{\mathrm{CH}}_3$ groups

⇒ order:- $\mathrm{a}>\mathrm{b}>\mathrm{d}>\mathrm{c}$
