Question

Which of the following molecule having resonating electronic configuration?

• A. $S{O}_2$
• B. $C_2{H}_6$
• C. $C{l}_2$
• D. $HBr$
• E. $NaCl$

Answer 1

The correct option is A $S{O}_2$

In chemistry, resonance or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure.Several Lewis structures are used collectively to describe the actual molecular structure, which is an approximate intermediate between the canonical forms called a resonance hybrid.Electron delocalization lowers the potential energy of the substance and thus makes it more stable than any of the contributing structures
