  Which of the following statements are correct about the reaction intermediate ? (a) Intermediate (III) is unstable because in this carbon is attached to 5 atoms. (b) Intermediate (HI) is unstable because carbon atom is sp2 hybridised. (c) Intermediate (DI) is stable because carbon atom is sp2 hybridised. (d) Intermediate (DI) is less stable than the reactant (II). Answer Q. No. 35 and 36 on the basis of the following reaction.

Answer:

  (A, D) Since the reaction occurs by  mechanism, therefore, rate of the reaction depends only upon the concentration of alkyl halide (II) and the molecularity of the reaction is one. Thus, options (a) and (c) are correct.
