Predict all the alkenes that would be formed by dehydrohalogenation of the
following halides with sodium ethoxide in ethanol and identify the major alkene:
(i) 1-Bromo-1-methylcyclohexane
(ii) 2-Chloro-2-methylbutane
(iii) 2,2,3-Trimethyl-3-bromopentane 6 11
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
