Acidity: H 2 O > HC ≡ CH > NH 3> CH 3 CH 3 Basicity: overset ominus OH < HC ≡ C ominus< overset ominus NH 2< CH 3 overset ominus CH 2

Q. What is the decreasing order of strengths of the following bases?
$O H, N H_{2}^{⊖}, H - C \equiv C$ , and $C H_{3} - C H_{2}^{⊖}$

$C H_{3} - C H_{2}^{⊖} > N H_{2}^{⊖} > H - C \equiv C^{⊖} > O ⊖ H$

$H - C \equiv C^{⊖} > C H_{3} - C H_{2}^{⊖} > N H_{2}^{⊖} > O ⊖ H$

$O ⊖ H > N H_{2}^{⊖} > H - C \equiv C^{⊖} > C H_{3} - C H_{2}^{⊖}$

$N H_{2}^{⊖} > H - C \equiv C^{⊖} > O ⊖ H > C H_{3} - C H_{2}^{⊖}$

Acidity: $H_{2} O > H C \equiv C H > N H_{3} > C H_{3} C H_{3}$
Basicity : $O ⊖ H < H C \equiv C^{⊖} < N ⊖ H_{2} < C H_{3} C ⊖ H_{2}$
