AIIMS 2018 Chemistry Reduction Reactions MCQ Question
Which of the following have maximum pH?
Black Coffee
Blood
Gastric Juice
Saliva
Correct Answer
Detailed Explanation
In the reaction, LiAlH₄ acts as a strong reducing agent that selectively reduces the imine group (−C=N−) to an amine group (−NH₂) without affecting the carbon-carbon double bond (C=C) present in the molecule. This selectivity is due to the steric and electronic properties of LiAlH₄, which allows it to target the electrophilic nitrogen in the imine while leaving the more stable alkene intact. Other options are not applicable as they do not provide relevant information or alternative reactions that pertain to the reduction process described.
