Reaction of a primary alkyl halide with AgCN followed by reduction with LiAlH4 will produce a primary amine.
True or False
False
True.
The reaction of a primary alkyl halide (R-X, where R is an alkyl group and X is a halide) with silver cyanide (AgCN) results in the formation of an alkyl cyanide (R-CN). This reaction is known as nucleophilic substitution.
Next, the alkyl cyanide can be reduced to a primary amine (R-NH2) by using a strong reducing agent, such as lithium aluminum hydride (LiAlH4). This reduction replaces the cyano group (-CN) with a hydrogen atom (-H), leading to the formation of the primary amine.
Therefore, the overall reaction sequence of primary alkyl halide → alkyl cyanide → primary amine is true.
True. When a primary alkyl halide (R-X) reacts with AgCN (silver cyanide), the cyanide ion (CN-) substitutes the halogen atom (X) to form a nitrile (R-CN). The nitrile can then be reduced to a primary amine (R-NH2) by treatment with LiAlH4 (lithium aluminum hydride). This reduction step replaces the triple bond in the nitrile with a hydride ion (H-) to form the primary amine.
To determine the reaction products, it is important to understand the reactivity and characteristics of the compounds involved. In this case, the nucleophilic substitution of the alkyl halide by the cyanide ion and the subsequent reduction of the nitrile to the primary amine can be deduced based on the specific reaction conditions and the reactivity of the reagents.
