Question

The maximum number of no bond resonating structure is possible in
​

Answer 1

Answer:

The maximum number of no bond resonating structure is possible in Option No. 4 i.e

         CH3

            I

H3C -- C -- CH3

           (+)  

This is because there are 9 hydrogen atoms next to (+) charge C atom. No bond resonance is commonly known as hyperconjugation.

Hyperconjugation is an extension of resonance as both methods cause the stabilization of a molecule through delocalization of electrons.

Answer 2

The maximum number of no bond resonating structure is possible in

Explanation:

No Bond resonance is also called as Hyper-conjugation .

Let us explain it :

HYPER CONJUGATION  

It is like resonance but the difference is that there is no bond present from where the electrons are shifted.  

The Condition required: It arises when = and – bond is at adjacent position.

• “More the terminal Hydrogen , more is the Hyper-conjugated structure.”

• We can define it as interaction between π electrons and adjacent bond of substituent group attached to it.  

• It is also called as Baker Nathan and non-bond resonance.

• It can explain stability of Alkylated alkenes.  

 

Out of the given compounds this condition is fulfilled by : Option 4 , as it has more terminal hydrogen.
