Out of NH3, PH3, AsH3 and SbH3 the most basic hydride is______

Answer: NH3

The most basic hydride is NH3. Basicity decreases in the order NH3 > PH3 > AsH3 > SbH3 > BiH3. As we move down the group, the stability of hydride decreases so NH3is most stable.

What is hydride?

In simple terms, the anion of hydrogen is referred to as hydride. Compounds of hydrogen with less electronegative elements are known as hydrides. It is a chemical compound where the hydrogen atoms exhibit nucleophilic, basic or reducing properties. Hydrides are hydrogen compounds that contain fewer electronegative elements. When hydrogen reacts with another substance, the resulting product is known as a hydride.
