Aldehydes & Ketones, Amines, Optical Isomerism

Question 1

Nucleophilic Addition ( addition of NaBH₄)

Answer 1

slightly acidic, aqueous
Reagent - NaBH
reaction -> REDUCTION
(does not work for carboxylic acids because needs a stronger reducing agent because it has OH & OR groups pushing electrons towards the carbon which makes it more stable)

Question 2

Nucleophilic Addition (addition of HCN)

Answer 2

• acidic conditions (for H⁺)
• aqueuous
  product: Hydroxynitriles
  reagent - KCN + dilute acid
