Convert : 1-chloropropane to 1-bromopropane
I am not sure that this is right or not. plz tell me if it is right otherwise give the right answer.
                                      Na
1-chloropropane    ------------------------->    Propene
              
             HBr / With Peroxide
Propene ----------------------->           1-bromopropane

arey budd
u cn do it in a much simpler way
use finkelstein reaction
that is one alkyl halide cn be converted into another alkyl halide wid same numbr of carbon atoms in d presence of d halide aslt in acetone medium

first treat it wlith alcoholic KOH.Alkene is formed and then treat the alkene with HBr

The heights by the great men reached and kept were not attained by a sudden flight ,but they while their companions slept were toiling upwards in the night.

!!

its ALCOHOLIC KOH!

@kuldud
isn't finkelstein reaction only for replacing any halogen by IODIDE!
we can replace any halogen by iodide using finkelstein or fluoride using swarts reaction...but i don't think that there is any reaction in which Br can replace Cl!

The electronegativity series is I>Br>Cl>F. So it is not possible to replace Br with Cl. So the original answer (Dehydrohalogenation and convert alkene to alky halide) is the correct answer.
