314414 Assertion :
Decreasing order of strength of bases is as
\(\mathrm{CH}_{3} \mathrm{CH}_{2}^{-}>\mathrm{NH}_{2}^{-}>\mathrm{HC} \equiv \mathrm{C}^{-}>\mathrm{OH}^{-}\)
Reason :
Acidic strength follows the order:
\({{\text{H}}_2}{\text{O}} > {\text{HC}} \equiv {\text{CH}} > {\text{N}}{{\text{H}}_2} > \)
\({\text{C}}{{\text{H}}_3} - {\text{C}}{{\text{H}}_3}\)

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
