phenolphthalein
Methyl amine reacts with methyl iodide. For completion of reaction, how many moles of methyl iodide are required ?
1
2
3
4
Complete the following reaction
RNH2 + H2SO4 →
[RNH3]+HSO-4
RNH2.H2SO4
no reaction
B.
Bases react with acid to form salt.
∴ Amines are basic in nature.
∴ It forms salt on reaction with H2SO4.
2RNH2 + H2SO4 →
