Question

The rule (or effect) which is applied in the following reaction is: CH3CHBrCH2CH3 overset A l c . K O H arrow (i) CH3CH=CHCH3 (major product) (ii) CH2=CHCH2CH3 (minor product) (A) Markownikoff's rule (B) Saytzeff's rule (C) Kharasch effect (D) Hofmann's rule

Tardigrade Admin · Accepted Answer

Alkyl halides on heating with alcoholic KOH give dehydrogenation reaction to yield alkene. If in reaction, more than one alkenes are formed, then according to Saytzeff, the most highly substituted alkene is the major product. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-brkrcsuxfh9eltua.jpg" />

Q. The rule (or effect) which is applied in the following reaction is:
$C H_{3} C H B r C H_{2} C H_{3} \to A l c . K O H$
(i) $C H_{3} C H = C H C H_{3}$ (major product)
(ii) $C H_{2} = C H C H_{2} C H_{3}$ (minor product)

Markownikoff's rule

Saytzeff's rule

Kharasch effect

Hofmann's rule

Alkyl halides on heating with alcoholic $K O H$ give dehydrogenation reaction to yield alkene. If in reaction, more than one alkenes are formed, then according to Saytzeff, the most highly substituted alkene is the major product.
