Convert but-1-ene to n-butyl iodide

Answer 1

ch3-ch2-ch=ch2+hbr↔ch3(ch2)3-br
ch3(ch2)3-br+nal↔ch3(ch2)3-1+NaBr.......convert

Answer 2

Hey dear,

● But-1-ene to n-butyl iodide -
But-1-ene is first converted to 1-bromobutane which then gives 1-iodobutane.

# Step 1 -
Butene is first treated with hydrogen bromide in presence of peroxide to give n-butyl bromide.
CH3-CH2-CH=CH2 + HBr --> CH3-CH2-CH2-CH2-Br

# Step 2 -
n-butyl bromide is then treated with sodium iodide in presence of dry acetone to form n-butyl iodide.
CH3-CH2-CH2-CH2-Br + NaI --> CH3-CH2-CH2-CH2-I + NaBr

Hope this helps you...
