Short Answer TypeHow do you convert:
i) Chlorobenzene to biphenyl
ii) propene to 1-iodopropane
iii) 2-bromobutane to but-2ene
Or
Write the major products(s) in the following:
(a) Draw the structures of major monohalo products in each of the following reactions :
(b) Which halogen compound in each of the following pairs will react faster in SN2 reaction:
(i) CH3Br or CH3I
(ii) (CH3)3C−Cl or CH3−Cl
Following compounds are given to you :
2-Bromopentane, 2-Bromo-2-methylbutane, 1-Bromopentane
(i) Write the compound which is most reactive towards SN2 reaction.
(ii) Write the compound which is optically active.
(iii) Write the compound which is most reactive towards b-elimination reaction.
(i) 1-bromopropane. Primary alkyl halides are most reactive for SN2.
(ii) 2-bromopentane: It has a unsymmetrical carbon atom. C2 is attached to 4 different groups i.e. methyl, propyl a dihydrogen atom.
(iii) 2-bromo-2-methyl butane: Tertiary alkyl halide is most reactive for elimination.
