प्रश्न

The correct order of increasing reactivity of C-X bond towards nucleophile in the following compounds is:

(I)

(II)

(III) (CH3)3 C-X

(IV) (CH3)2 CH-X

पर्याय

  • I < II < III < IV

  • II < I < III < IV

  • III < IV < II < I

  • IV < III < I < II

  • I < II < IV < III

MCQ

उत्तर

I < II < IV < III

Explanation:

Alkyl halides are more reactive than aryl halides. This is because of the partial double bond character between the benzene ring and the halogen. Further, in alkyl halides, the greater the stability of carbocation formed, the more would be the reactivity. Thus, the tertiary halide is more reactive. Nitro group which is electron-withdrawing increases the reactivity of aryl halide.
