EN order of hybridized carbons

EN order of hybridized carbons
SP3 C {EN Value: 2.5} < SP2 C {EN Value: 2.75} < SP C {EN Value: 3.25}  [SP C: ≈50% S Character]


Example:
1.      CH3-->--C≡N  {-I effect of -C≡N  (-CH3 :- Sp3C   &  -C≡N :- Sp C)}
                          Note: {Order of EN :-   C+  > C > C-}
2.      CH3-->--NH2
3.      CH3-->>--N+H3  
                                Note: {-I effect of –N+H3  >  -NH2}
