Convert 1 chlorobutane to 1 iodobutane
The conversion of but-1-ene to 1-iodobutane takes place according to anti-markovnikoff (positive charged ion H + goes to the carbon which has less number of hydrogens and negative part Br- goes to the carbon which has more number of hydrogens.) i.e. the attack of HBr on but-1-ene in the presence of peroxide gives 1-bromobutane as the intermediate which on treatment with NaI+Acetone gives 1 1-chlorobutane did not form a precipitate, even in the presence of heat. For the effect of the substrate on an SN2 reaction, five test tubes were obtained. 0.1 mL of 1-chlorobutane was placed in the first test tube. 0.1 mL of 1-bromobutane was placed in the second test tube. 0.1 mL of 2-chlorobutane was placed in the third test tube. How will you bring about the following conversions? (i) Ethanol to but-1-yne (ii) Ethane to bromoethene (iii) Propene to 1-nitropropane (iv) Toluene to benzyl alcohol (v) Propene to propyne (vi) Ethanol to ethyl fluoride (vii) Bromomethane to propanone (viii) But-1-ene to but-2-ene (ix) 1-Chlorobutane to n-octane (x) Benzene to biphenyl. This is again an example of nucleophilic substitution. This time the slow step of the reaction only involves one species - the halogenoalkane. It is known as an S N 1 reaction. The reaction of secondary halogenoalkanes with hydroxide ions. The facts. The facts of the reaction are exactly the same as with primary or tertiary halogenoalkanes. 6.20 (a) 1-Bromopropane would react more rapidly because, being a primary halide, it is less hindered. (b) 1-Iodobutane, because iodide ion is a better leaving group than chloride ion. (c) 1-Chlorobutane, because the carbon bearing the leaving group is less hindered than in 1-chloro-2-methylpropane.
