Regarding the hydrides of group 15 elements \( EH_{3} \) (E = N, P, As, Sb), select the correct statement from the following:
A. The stability of hydrides decreases down the group.
B. The basicity of hydrides decreases down the group.
C. The reducing character increases down the group.
D. The boiling point increases down the group.
Choose the correct answer from the options given below:
- A A, B & C only
- B A & D only
- C A, B, C & D
- D B & C only
Answer & Solution
Correct Answer
(A) A, B & C only
Step-by-step Solution
Detailed explanation
Stability: \( NH_{3}>PH_{3}>AsH_{3}>SbH_{3}>BiH_{3} \) Basicity: \( NH_{3}>PH_{3}>AsH_{3}>SbH_{3}>BiH_{3} \) Reducing character : \(NH _3< PH _3< AsH _3< SbH _3< BiH _3\) Boiling point: \(PH _3< AsH _3< NH _3< SbH _3< BiH _3\)
