Question 4

When 1-pentanol is heated with HCl/ZnCl₂, 1-chloropentane is the major organic product. This reaction proceeds through an ________ mechanism, and ________ is produced as a byproduct.

Accepted Answer

The reaction of 1-pentanol with HCl/ZnCl2 follows an SN2 mechanism, in which the hydroxyl group is replaced by a chloride ion to form 1-chloropentane. Zinc chloride is produced as a byproduct. Option B correctly identifies the mechanism and byproduct of the reaction. Option A incorrectly identifies the byproduct as hydrogen sulfide, which is not involved in this reaction. Option C correctly identifies the byproduct but incorrectly identifies the mechanism as SN1, which is not the case for this reaction. Option D incorrectly identifies both the mechanism and byproduct. Option E refers to a different type of reaction mechanism (elimination) that does not apply to this reaction.

Question 5

Give the major organic product for the following reaction.

Accepted Answer

The given reaction involves the reaction of an alkene with peroxyacid MCPBA (meta-chloroperoxybenzoic acid), which results in the formation of an epoxide. The product formed in this reaction will be an epoxide having the addition of an oxygen atom to the double bond. Only option C shows the formation of such an epoxide product. Hence, option C is the correct answer.

Question 8

Which of the following alcohols will react most rapidly with the Lucas reagent (HCl, ZnCl₂)?

Accepted Answer

The Lucas reagent reacts most rapidly with tertiary alcohols due to their ability to form more stable carbocations. Option A represents a tertiary alcohol, where the hydroxyl group is attached to a carbon atom that is itself connected to three other carbon atoms.

Question 9

Which of the following is the best method for preparing CH₃Br?

Accepted Answer

HBr is the best choice for preparing CH₃Br as it will directly react with CH₃OH to form the desired product. The other options either have unnecessary or incorrect reactants.

Question 13

Give the major organic product for the following reaction.

Accepted Answer

The given reaction is a nucleophilic substitution reaction with t-butyl chloride as the substrate and sodium methoxide as the nucleophile. Sodium methoxide is a strong base and nucleophile and undergoes an SN2 reaction with t-butyl chloride to displace chloride and form t-butyl methoxide. Hence, the major organic product is option C, which shows the formation of t-butyl methoxide. The other options do not represent the correct product of the given reaction.
