Question

Reactivity of hydrogen atoms attached to different carbon atoms in alkanes has the order:

• A. Tertiary > Primary > Secondary
• B. Primary > Secondary > Tetriary
• C. Both (a) and (b)
• D. Tetriary > Secondary > Primary

Answer 1

The correct option is D Tetriary > Secondary > Primary

The reactivity of H-atoms depend upon the stability of free radicals follows the order : Tertiary > Secondary > Primary, therefore, reactivity of H-atoms follows the same order, i.e., tertiary > secondary > primary.
