CBSE Class 12 · 2000 · Delhi · Compounds Containing NitrogenVery Short Answer

For an amine RNH₂, write the expression for K_b to indicate its base strength.

Answer: K_b = [RNH₃⁺][OH⁻]/[RNH₂].

Solution

RN H_{2} + H_{2} O ⇌ RN H_{3}^{+} + O H^{-}

K_{b} = \frac{[ R N H _{3}^{+} ] [ O H ^{-} ]}{[ R N H _{2} ]}
