Question
The increasing order of reduction of alkyl halides with zinc and dilute HCl is ______.
Options
R – Cl < R – I < R – Br
R – Cl < R – Br < R – I
R – I < R – Br < R – Cl
R – Br < R – I < R – Cl
Solution
The increasing order of reduction of alkyl halides with zinc and dilute HCl is R – Cl < R – Br < R – I.
Explanation:
The reactivity of reduction bf alkyl halides with Zn/HCl increases as the strength of the C – X bond decreases, i.e., R – Cl < R – Bf < R – I.
