SR Aldehyde 2M

Question 1

Aldehyde => Hydroxynitrile
Equation
Type of reaction
Reagents 
Draw mechanism

Answer 1

Equation
                            H2SO4
-Aldehyde + HCN => Hydroxynitrile 
                            NaCN
Type of Reaction 
-Nucleophilic Addition

Reagents

• NaCN
• H2SO4

*HCN is too poisonous to use so to increase reaction rate in the presence of cyanide ions so use a mix of NaCN and H2SO4 to improve rate of reaction and safety
