Among the hydrides of Group-15 elements, which have the
maximum reducing character

Explanation

To determine which hydride of Group 15 elements has the maximum reducing character, we can follow these steps:

### Step 1: Identify the Group 15 Elements
Group 15 elements include Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi). The hydrides formed by these elements are NH3 (Ammonia), PH3 (Phosphine), AsH3 (Arsine), SbH3 (Stibine), and BiH3 (Bismuthine).

**Hint:** Remember that reducing character is related to the ability of a substance to donate electrons.
