JEE Main 2026 · 8 Apr · Shift 2, Chemistry question 59

Find the correct statements related to group 15 hydrides.

A. Reducing nature increases from NHX3\ce{NH3} to BiHX3\ce{BiH3}

B. Tendency to donate lone pair of electrons decreases from NHX3\ce{NH3} to BiHX3\ce{BiH3}

C. The stability of hydrides decreases from NHX3\ce{NH3} to BiHX3\ce{BiH3}

D. HEH bond angle decreases from NHX3\ce{NH3} to SbHX3\ce{SbH3} (E = Elements of group 15)

Choose the correct answer from the options given below :

Answer and worked solution

Official answer: C

Down group 15 (NH₃ to BiH₃):

  • Reducing nature increases, as the E-H bond weakens.
  • Basicity (lone-pair donation) decreases.
  • Thermal stability decreases.
  • Bond angle falls from 107° (NH₃) to about 91° (SbH₃).

All four are correct.
