The reactions are given above:
(i) 1-methylcyclohexene is the major product.
Only one alkene is formed at beta H atoms on either side of Br atoms are equivalent.
Only one alkene is formed at beta H atoms on either side of Br atoms are equivalent.
(ii) 2-methyl-2-butene is the major product.
Two different alkenes are formed. More substituted alkene is the major product as it is more stable. This is in accordance with Saytzeff's rule.
Two different alkenes are formed. More substituted alkene is the major product as it is more stable. This is in accordance with Saytzeff's rule.
(iii) 3,4,4-Trimethylpent-2-ene is the major product.
Two different alkenes are formed. More substituted alkene is the major product as it is more stable. This is in accordance with Saytzeff's rule.
