The correct order in aqueous medium of basic strength in case of methyl substituted amines is :
- A \(Me _2 NH > MeNH _2 > Me _3 N > NH _3\)
- B \(Me _2 NH > Me _3 N > MeNH _2 > NH _3\)
- C \(NH _3 > Me _3 N > MeNH _2 > Me _2 NH\)
- D \(Me _3 N > Me _2 NH > MeNH _2 > NH _3\)
Answer & Solution
Correct Answer
(A) \(Me _2 NH > MeNH _2 > Me _3 N > NH _3\)
Step-by-step Solution
Detailed explanation
In aqueous medium basic strength is dependent on electron density on nitrogen as well as solvation of cation formed after accepting \(H ^{+}\). After considering all these factors overall basic strength order is \(Me _2 NH > MeNH _2 > Me _3 N > NH _3\)
