Question

which of the following represents the correct order of stability of the given carbocation

Answer 1

In 1st image, On the basis of number of resonating structure, last option is correct option.  

In 2nd image, the 3rd structure is aromatic and is more stable whereas 2nd structure is anti aromatic and is unstable. The 1st structure is more stabilized by resonance and hence the order of stability would be :

3rd > 1st > 2nd
