• # question_answer Which of the following orders regarding relative stability of free radicals is correct [UPSEAT 2004] A) $3{}^\circ <2{}^\circ <1{}^\circ$ B) $3{}^\circ \text{ }>\text{ }2{}^\circ \text{ }>\text{ }1{}^\circ$ C) $1{}^\circ \text{ }<\text{ }2{}^\circ \text{ }>\text{ }3{}^\circ$ D) $3{}^\circ \text{ }>\text{ }2{}^\circ \text{ }<\text{ }1{}^\circ$

Correct Answer: B

Solution :

Due to the increasing no. of hyperconjugative structures free radical stabilise following as $3{}^\circ >2{}^\circ >1{}^\circ$.
