Question

The correct order in aqueous medium of basic strength in case of methyl substituted amines is : (A) NH 3> Me 3 N > MeNH 2> Me 2 NH (B) Me 2 NH > Me 3 N > MeNH 2> NH 3 (C) Me 2 NH > MeNH 2> Me 3 N > NH 3 (D) Me 3 N > Me 2 NH > MeNH 2> NH 3

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

M e_{2} N H > M e N H_{2} > M e_{3} N > N H_{3}

Q. The correct order in aqueous medium of basic strength in case of methyl substituted amines is :

$N H_{3} > M e_{3} N > M e N H_{2} > M e_{2} N H$

$M e_{2} N H > M e_{3} N > M e N H_{2} > N H_{3}$

$M e_{2} N H > M e N H_{2} > M e_{3} N > N H_{3}$

$M e_{3} N > M e_{2} N H > M e N H_{2} > N H_{3}$

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
$M e_{2} N H > M e N H_{2} > M e_{3} N > N H_{3}$

Q. The correct order in aqueous medium of basic strength in case of methyl substituted amines is :

NH3​>Me3​N>MeNH2​>Me2​NH

Me2​NH>Me3​N>MeNH2​>NH3​

Me2​NH>MeNH2​>Me3​N>NH3​

Me3​N>Me2​NH>MeNH2​>NH3​

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 Me2​NH>MeNH2​>Me3​N>NH3​

$N H_{3} > M e_{3} N > M e N H_{2} > M e_{2} N H$

$M e_{2} N H > M e_{3} N > M e N H_{2} > N H_{3}$

$M e_{2} N H > M e N H_{2} > M e_{3} N > N H_{3}$

$M e_{3} N > M e_{2} N H > M e N H_{2} > N H_{3}$

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
$M e_{2} N H > M e N H_{2} > M e_{3} N > N H_{3}$
