Predict the major product of acid catalysed dehydration:
(i) 1-methyl cyclohexanol
(ii) Butan-1-ol

Question

Predict the major product of acid catalysed dehydration-i- 1-methyl cyclohexanol-ii- Butan-1-ol

Toppr Admin · Accepted Answer

Due to Saytzeff rule- in -i- the product where double bond is formed at the more substituted carbon is the major product- But as Saytzeff rule is only valid for 2-xB0- and 3-xB0- alcohols- a primary alcohol like -ii- will form a terminal alkene as the major product-

Predict the major product of acid catalysed dehydration:(i) 1-methyl cyclohexanol(ii) Butan-1-ol

Due to Saytzeff rule, in (i) the product where double bond is formed at the more substituted carbon is the major product. But as Saytzeff rule is only valid for 2° and 3° alcohols, a primary alcohol like (ii) will form a terminal alkene as the major product.

(i) 1-methyl cyclohexanol
(ii) Butan-1-ol

Due to Saytzeff rule, in $(i)$ the product where double bond is formed at the more substituted carbon is the major product. But as Saytzeff rule is only valid for 2° and 3° alcohols, a primary alcohol like $(i i)$ will form a terminal alkene as the major product.
