Which of the following molecules is least resonance stabilized?
The Correct Option is B
Solution and Explanation
However, all molecules given in options are stabilised by resonance but compound given in option (B) is least resonance stabilised (other three are aromatic)
So, the correct option is (B).

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
