Arrange the following in correct order of their basic strength (I) \(

1.	Arrange the following in correct order of their basic strength (I) \( OH ^{-} \) (II) \( CH _{3} COO ^{-} \) (III) \( Cl ^{-} \) a) \( III > Il > I \) b) \( I > II > III \) c) \( I > III > II \) d) \( I I>I I I>I \)
Answer» Correct option is (b) CH₃COO^- As we know that stronger the base, weaker the its conjugate acid. The conjugate acids \(\bar O\)H \(\longrightarrow\) H₂O CH₃COO^-\(\longrightarrow\) CH₃COOH Cl^- \(\longrightarrow\) Hcl As we know , HCl is stronger acid than H₂O and CH₃COOH,. CH₃COOH is stronger acid than H₂O Therefore the order of basic strength of \(\bar O\)H, CH₃COO^-and Cl^-will be \(\bar O\)H > CH₃COO^- > Cl^-

Answer»

Correct option is (b) CH₃COO^-

As we know that stronger the base, weaker the its conjugate acid.

The conjugate acids

\(\bar O\)H \(\longrightarrow\) H₂O

CH₃COO^-\(\longrightarrow\) CH₃COOH

Cl^- \(\longrightarrow\) Hcl

As we know , HCl is stronger acid than H₂O and CH₃COOH,. CH₃COOH is stronger acid than H₂O

Therefore the order of basic strength of \(\bar O\)H, CH₃COO^-and Cl^-will be

\(\bar O\)H > CH₃COO^- > Cl^-
