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

Predict all the alkenes that would be formed by the dehydrohalogenatio

1.	Predict all the alkenes that would be formed by the dehydrohalogenation of the following halides with sodium ethoxide and identify the major alkene : (i) 2-Chloro-2-methylbutane (ii) 2, 2, 3-trimethyl-3-bromopentane (iii) Cyclohexylmethyl bromide (iv) 1-Bromo-1-methylcyclohexane
Answer» Solution :(i) 2-Methylbut-2-ene (MAJOR) + 2-methylbut-1-ene (II) 3,4,4-Trimethylpent-2-ene (major) + 2,3,3-trimethylpent-1-ene (III) 1-Methylcyclohexene (major) + methylene cyclohexane (IV) same as (iii)
