Question
What is the decreasing order of strength of the bases OH-, NH2-, H - C ≡ C- and CH3 - CH2- ?
Options
A.CH3 - CH2- > NH2- > H - C ≡ C- > OH-
B.H - C ≡ C- > CH3 - CH2- > NH2- > OH-
C.OH- > NH2- > H - C ≡ C- > CH3 - CH2-
D.NH2- > H - C ≡ C-> OH- > CH3 - CH2-
Solution
Conjugate base of dtrong acid weaker while conjugate base of weak acid is stronger because the acidic strength folloes the order. Thus
H - OH > HC ≡ CH > NH3 > CH3 - CH3
Order of basic strength :
CH3CH2- >
> HC ≡ C- < OH-
H - OH > HC ≡ CH > NH3 > CH3 - CH3
Order of basic strength :
CH3CH2- >
> HC ≡ C- < OH- Create a free account to view solution
