JEE Main 30 January 2024, Shift 2, Chemistry Q67

Question 67 of 90 in this shift, Chemistry question 7 of 30, Section A.

Choose the correct statements about the hydrides of group 15 elements. A. The stability of the hydrides decreases in the order NH3>PH3>AsH3>SbH3>BiH3\mathrm{NH_3} > \mathrm{PH_3} > \mathrm{AsH_3} > \mathrm{SbH_3} > \mathrm{BiH_3}. B. The reducing ability of the hydride increases in the order NH3<PH3<AsH3<SbH3<BiH3\mathrm{NH_3} < \mathrm{PH_3} < \mathrm{AsH_3} < \mathrm{SbH_3} < \mathrm{BiH_3}. C. Among the hydrides, NH3\mathrm{NH_3} is strong reducing agent while BiH3\mathrm{BiH_3} is mild reducing agent. D. The basicity of the hydrides increases in the order NH3<PH3<AsH3<SbH3<BiH3\mathrm{NH_3} < \mathrm{PH_3} < \mathrm{AsH_3} < \mathrm{SbH_3} < \mathrm{BiH_3}.
