Question

Covalent bonds can undergo fission in two different ways. The correct representation involving the heterolytic fission of CH – br is

(a) 

(b) 

(c) 

(d) 

Answer 1

Arrow denotes the direction of movement of electrons. Since, Br is more electronegative than carbon, heterolytic fission occurs in such a way that CH gets the positive charge and Br gets the negative charge. 

Thus, option (b) is correct.
