The overall conversion RBr $\to$ RCH₂NH₂ can be accomplished by successive application of which of these sets of reagents? A)Mg,ether; then NH₃ B)NaN₃; then LiAlH₄,ether C)NaCN; then LiAlH₄,ether D)H₂C=O; then NH₃ E)H₂NOH; then LiAlH₄,ether

Question

Quizplus · Accepted Answer

The conversion described involves changing an alkyl bromide (RBr) into an alkyl cyanide (RCN) and then reducing the nitrile group to a primary amine (RCH2NH2). Choice C, NaCN followed by LiAlH4 in ether, correctly outlines the steps for this transformation: NaCN substitutes the bromide with a cyanide group, and LiAlH4 then reduces the nitrile group to a primary amine.
