Question

The correct decreasing order of basic strength of the following species is (A)  OH->NH2->H2O>NH3  (B)  NH2->OH->NH3>H2O  (C)  NH3>H2O>NH2->OH-  (D)  H2O>NH3>OH->NH2-

NH3 is more basic than H2O, therefore, NH2- is a stronger base than OH- . Thus, the decreasing order of basic strength is NH2->OH->NH3>H2O

Q. The correct decreasing order of basic strength of the following species is

$O H^{-} > N H_{2}^{-} > H_{2} O > N H_{3}$

$N H_{2}^{-} > O H^{-} > N H_{3} > H_{2} O$

$N H_{3} > H_{2} O > N H_{2}^{-} > O H^{-}$

$H_{2} O > N H_{3} > O H^{-} > N H_{2}^{-}$

$N H_{3}$ is more basic than $H_{2} O,$ therefore, $N H_{2}^{-}$ is a stronger base than $O H^{-}$ . Thus, the decreasing order of basic strength is $N H_{2}^{-} > O H^{-} > N H_{3} > H_{2} O$

Q. The correct decreasing order of basic strength of the following species is

OH−>NH2−​>H2​O>NH3​

NH2−​>OH−>NH3​>H2​O

NH3​>H2​O>NH2−​>OH−

H2​O>NH3​>OH−>NH2−​

NH3​ is more basic than H2​O, therefore, NH2−​ is a stronger base than OH− . Thus, the decreasing order of basic strength is NH2−​>OH−>NH3​>H2​O

$O H^{-} > N H_{2}^{-} > H_{2} O > N H_{3}$

$N H_{2}^{-} > O H^{-} > N H_{3} > H_{2} O$

$N H_{3} > H_{2} O > N H_{2}^{-} > O H^{-}$

$H_{2} O > N H_{3} > O H^{-} > N H_{2}^{-}$

$N H_{3}$ is more basic than $H_{2} O,$ therefore, $N H_{2}^{-}$ is a stronger base than $O H^{-}$ . Thus, the decreasing order of basic strength is $N H_{2}^{-} > O H^{-} > N H_{3} > H_{2} O$
