The following are some statements related to VA group hydrides, I. Reducing property increases from NH ₃ to BiH ₃ . II. Tendency to donate lone pair decreases from NH ₃ to BiH ₃ . III. Thermal stability of hydrides decreases from NH ₃ to BiH ₃ . IV. Bond angle of hydrides decreases from NH ₃ to BiH ₃ . The correct statements are
Options
- AI, II, III and IV
- BI, III and IV
- CI, II and IV
- DI and IV
Correct answer
A. I, II, III and IV
Step-by-step solution
The reducing property of the hydrides of VA group increases from NH ₃ to BiH ₃ NH ₃ PH ₃> AsH ₃> SbH ₃> BiH ₃ Bond angle of VA group hydrides decreases from NH ₃ to BiH ₃ NH ₃> PH ₃> AsH ₃> SbH ₃> BiH ₃
