REACTION MECHANISM(QUIZ-4) 1 / 5 "The negative part of the addendum adds on the carbon atom joined to the least number of hydrogen atoms." This statement is called as: Markownikoff's rule Peroxide effect Baeyer's strain theory Thiele's theory it is Markownikoff's rule. 2 / 5 Hydrolysis of propane gives: methyl and ethyl free radicals methylium cation and ethyl anion methyl anion and ethylium cation methylium and ethylium cations 3 / 5 Carbanions initiate: addition reactions substitution reaction both (a) and (b) none of these Carbanions are nucleophilic species that can initiate both addition and substitution reactions. They can attack electrophilic centers in molecules, leading to addition reactions, or displace leaving groups, resulting in substitution reactions. 4 / 5 The SN2 mechanism for R-X + KOH (aq) →→ R-OH + KX follows with: 100% inversion 50% inversion 40% inversion 30% inversion The SN2 mechanism always involves 100% inversion since nucleophile attack from back side of leaving group. 5 / 5 Which of the following is an example of the elimination reaction?
