Predict the major, organic product for the following reaction.

The figure illustrates the structure of a molecule. A 3-carbon alkane chain is depicted as a line structure using 2 zigzag lines. C 2 is single bonded to C H 3 on the lower left and C H 3 on the lower right, each in the form of a line. C 3 is single bonded to N H 2 above.

Verified step by step guidance

Identify the functional group in the starting material. The given compound is an amide, characterized by the presence of a carbonyl group (C=O) directly bonded to a nitrogen atom (N).

Recognize the reagent used in the reaction. Lithium aluminum hydride (LiAlH4) is a strong reducing agent commonly used to reduce amides to amines.

Understand the mechanism of the reaction. LiAlH4 reduces the carbonyl group in the amide to a methylene group (CH2), effectively converting the amide into an amine.

Predict the structure of the product. The carbonyl oxygen is removed, and the carbonyl carbon is converted to a methylene group, resulting in the formation of a primary amine.

Draw the major organic product. The amide is reduced to an amine, with the carbonyl group replaced by a CH2 group, resulting in a compound with an NH2 group attached to the carbon chain.
