Draw the possible resonance for `CH_(3)- underset(..)overset(..)(O)-overset(+)(C)H_(2)` and predict which of the structures is more stable. Give reason for your answer.

'Stability of carbocations depends upon the electron releasing inductive effect of groups adjacent to positively charged atom involvement of neighbouring groups in hyperconjugation and resonace''. Draw the possible resonance structures for CH_(3) - underset(..)overset(..)(O) - overset(+)(C) H_(2) and predict which of the structures is more stable. Give reason for your answer.

The most stable resonating structure of CH_(3)-underset(* *)overset(* *)O=CH is :

The nitrite ion can be represented, {:(,"I."[:overset(..)underset(..)O-overset(..)N=overset(..)underset(..)O]^(-)),([overset(..)underset(..)O=overset(..)N-overset(..)underset(..)O:]^(-),),(,"II."[overset(..)underset(..)N=overset(..)O-overset(..)underset(..)O:]^(-)):} Which of the structure represents possible resonance forms of this ion?

Resonance structures of propenal are given below. Which of these resonating structures is more stable ? Give reason for your answer. CH_(2)=underset("I")(CH-CH)=O harr underset("II")(overset(o+)(CH)_(2)-CH=CH-overset(Theta)(O))
