4) (marks-1.5) Please answer the following as TRUE or FALSE in the space provided to the left of each statement (0.5 marks each). True/False a) Tertiary alkyl halides only participate in SN1 reactions. b) CH3O- is a better nucleophile for an SN2 reaction than CH3S-when in methanol. c) Complete hydrogenation of Limonene (drawn below) will produce two stereoisomers.

True/False Indicate whether the statement is (A) true or (B) false. In the most stable conformation of a cyclohexane, it is preferable to have as many substituents in the axial position as possible. 2. 3. Syl reactions may involve a carbocation rearrangement. Tertiary alkyl halides are more likely to participate in an Sy2 reaction. 4. Cis-1,3-dimethyleyclohexane and trans-1,3-cyclohexane are enantiomers. 5. 6. An Sy2 reaction results in inversion of the relative configuration. The rate of an SNl reaction can be...

13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as SNI (substitution, nucleophilic, unimolecular) and S 2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the Sy2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Syl reaction involves rapid protonation of the alcohol, followed by...

Total Marks 53 Q1. True / False 1. Tertiary hydrogen is more reactive than secondary hydrogen towards chlorination. 2. Tertiary alcohol is less reactive towards HX than secondary alcohol. 3. Loss of electron density by carbon is called reduction. 4. SN2 is a twostep reaction. 5. In SN2 the stereochemistry at C is not inverted. 6. Smaller activation energy makes the reaction slow. 7. Bulky substrate favors the rate of SN? reaction. 8. Neutral nucleophiles are more favorable for SN...
