Question

Which of the following applies in the reaction, CH 3 CHBrCH 2 CH 3 xrightarrow Alc.KOH (i) CH 3 CH = CHCH 3 (major product) (ii) CH 2= CHCH 2 CH 3 (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 dehydrohalogenation 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-ba4winu00htymhdx.jpg" />

Markownikoff's rule

Saytzeff's rule

Kharasch effect

Hofmann's rule

Alkyl halides on heating with alcoholic $K O H$ give dehydrohalogenation 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.
