Organic Reaction Mechanisms and Pathways starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Organic Reaction Mechanisms and Pathways.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Describe the difference between syn and anti addition in organic reactions.
Describe the mechanism of the bromination of benzene.
Describe the steps involved in the E1 elimination mechanism.
Explain the difference between nucleophilic substitution and electrophilic substitution reactions.
Explain the role of a catalyst in the Friedel-Crafts alkylation reaction.
Explain why primary alkyl halides are more reactive in SN2 reactions than tertiary alkyl halides.
Explain why tertiary alkyl halides do not undergo SN2 reactions efficiently.
In the context of organic reaction mechanisms, what is meant by the term 'leaving group'?
Which of the following is a characteristic of a nucleophile? (1) Electron-deficient (2) Electron-rich (3) Positively charged (4) Non-polar
Which of the following is a feature of the E2 mechanism? (1) Involves a carbocation intermediate (2) Proceeds via a concerted mechanism (3) Favored by weak bases (4) Occurs in two steps
Which of the following is a nucleophile? (1) NO2+ (2) Cl- (3) SO3 (4) H+
Which of the following is a possible product when 2-bromobutane undergoes E2 elimination? (1) 1-butene (2) 2-butene (3) 2-butanol (4) 1-butanol
In the E2 elimination mechanism, the base removes a proton from the carbon atom ________ to the leaving group.
In the reaction of benzene with CH3Cl and AlCl3, the electrophile generated is ________.
The intermediate formed during the addition of Br2 to ethene is a ________ ion.
The intermediate formed during the electrophilic addition of HBr to propene is a ________ ion.
The rate law for an SN2 reaction is rate = k[substrate][nucleophile]. True or False?
True or False: In the SN1 mechanism, the rate of reaction depends only on the concentration of the substrate.
True or False: The addition of Br2 to an alkene is an example of a syn addition.
True or False: The E1 mechanism involves the formation of a carbocation intermediate.
