5. Explain
6. Convert the following.
i. Propene to propan-1-ol
ii. Benzyl alcohol to benzyl cyanide
iii. Ethanol to propane nitrile
iv. But-1-ene to n-butyl iodide
v. 2-Chloropropane to propan-1-ol
vi. tert-Butyl bromide to isobutyl bromide
vii. p-Nitrochlorobenzene to p-nitrophenol
viii. Propene to 1-nitropropane
Answer:-
2
3) \[\ce{\underset{\text{But-1-ene}}{CH3 - CH2 - CH = CH2 + HBr}->[Peroxide] \underset{\text{1-Bromobutane}}{CH3 - CH2 - CH2 - CH2Br}}\]
4) \[\ce{\underset{\text{1-Bromobutane}}{CH3 - CH2 - CH2 - CH2Br + NaI} ->[Acetone]\underset{\text{n-Butyl iodide (1-Iodobutane)}}{CH3 - CH2 - CH2 - CH2I + NaBr↓}}\]
5)\[\begin{array}{cc}
\ce{H3C - CH - CH3 ->[Alc.KOH]\underset{Propene}{H3C - CH = CH2}->[HBr][Peroxide]\underset{1-Bromopropane}{H3C - CH2 - CH2Br}->[NaOH(aq.)]\underset{Propan-1-ol}{H3C - CH2 - CH2OH}}\\
