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.

Explanation
Another way of rationalising is through the use of the Hard-Soft Acid-Base principle. The dichlorocarbene generated is a soft electrophilic species while the oxyanion form of the phenoxide is a hard nucleophilic species. The nucleophilic pi bond is much softer and thus, it is much more favourable for it to be the attacking nucleophile (soft-soft interaction) rather than the negatively-charged oxygen atom (hard-soft interaction).
sir what is ordered transition state
In general, an associative mechanism occurs when the entropy of the transition state is lower than the reactants and thus the transition state is more ordered.
