Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Stability of resonating structures depends on the following- Number of π bonds ∝ Resonance energy ∝ stability. Contributing structures should be such that the negative charge resides on an electronegative element and positive charge resides on an electropositive element. In contributing structures, like charges should not reside on atoms close to each other and unlike charges should be widely separated.
First check number of covalent bonds..More covalent bond more stability
IV is least stable as there are 3 covalent bonds and electronegative oxygen contain positive charge
Ist is most stable as there are 4 covalent bond and no charge separation
sir second aur third main
second less hoga 3rd se
less covalent bond
got shweta
yes sir🙂
check previous answer too shweta
sir
