Reaction Mechanism(QUIZ-5) 1 / 5 Reaction intermediate of E1 reaction is: Carbocation carbanion Carbene free radical In an E1 reaction, the rate-determining step involves the formation of a carbocation intermediate by the heterolytic cleavage of a carbon-hydrogen or carbon-carbon bond. This carbocation then undergoes elimination of a proton to form an alkene product. 2 / 5 Which compound will form Schiff base with carbonyl compounds? p-amines sec-amines bydroxylamine Hydrazine 3 / 5 Which among the following compounds has minimum pH value? butane 2-butene 1-butyne 2-butyne Among the given options, 1-butyne has the minimum pH value as the triple bond is more acidic than double and single bonds due to the greater s-character of the sp-hybridized carbon atom, making the hydrogen more acidic. 4 / 5 In an SN1 reaction on chiral centres there is 100% racemisation inversion more than retention leading to partial racemisation 100% retention 100% inversion In SN1 reaction, there is slight more inversion product than retention product because SN1 reaction also depends on shielding effect of the front side of the reacting carbon. 5 / 5 The formation of cyanohydrin from a ketone is an example of: electrophilic addition nucleophilic addition nucleophilic substitution electrophilic substitution The formation of cyanohydrin from a ketone is an example of a nucleophilic addition reaction. In this reaction, the cyanide ion (CN⁻) acts as a nucleophile and attacks the electrophilic carbonyl carbon of the ketone, forming a cyanohydrin product.
