Find the correct statements related to group 15 hydrides.
A. Reducing nature increases from NH\(_3\) to BiH\(_3\)
B. Tendency to donate lone pair of electrons decreases from NH\(_3\) to BiH\(_3\)
C. The stability of hydrides decreases from NH\(_3\) to BiH\(_3\)
D. HEH bond angle decreases from NH\(_3\) to SbH\(_3\) (E = Elements of group 15)
Choose the correct answer from the options given below:
- A A and B only
- B B and C only
- C A, B, C and D
- D A, C and D Only
Answer & Solution
Correct Answer
(C) A, B, C and D
Step-by-step Solution
Detailed explanation
Statement A: The reducing nature of group 15 hydrides depends on the E-H bond strength. As the size of the central atom increases down the group, the E-H bond dissociation enthalpy decreases. Hence, the reducing character increases from NH\(_3\) to BiH\(_3\). This statement is…
