प्रश्न
Covalent bond can undergo fission in two different ways. The correct representation involving a heterolytic fission of CH3 – Br is:
पर्याय
उत्तर
Explanation:
Br is more electronegative than C, hence heterolytic fission takes place. Electrons displace from carbon to Br. Therefore, CH3 gets positive charge and Br gets negative charge.
