Which of the following order of basic strength is correct?
Options
- ANH ₃ < NH ₂ OH < HN ₃ < NH ₂- NH ₂
- BNH ₂ OH < HN ₃ < NH ₂- NH ₂ < NH ₃
- CHN ₃ < NH ₃ < NH ₂ OH < NH ₂- NH ₂
- DHN ₃ < NH ₂ OH < NH ₂- NH ₂ < NH ₃
Correct answer
B. NH ₂ OH < HN ₃ < NH ₂- NH ₂ < NH ₃
Step-by-step solution
Basicity in nitrogen compounds is attributed to the availability of lone pair of electrons. The order of availability of e⁻ pair on N -atom is NH ₃> NH ₂ NH ₂> HN ₃> NH ₂ OH Therefore, same is the order of basicity of these compounds.
