The bond angles of NH3, PH3, AsH3, and SbH3 are in the order of NH3 PH3 AsH3 SbH3.

Here's why:

1. The bond angle in a molecule is determined by the repulsion between the electron pairs in the valence shell of the central atom. This is known as the Valence Shell Electron Pair Repulsion (VSEPR) theory.

2. According to the VSEPR theory, the electron pairs will arrange themselves to be as far apart from each other as possible, to minimize repulsion. This results in a specific shape and bond angle for the molecule.

3. In the case of NH3, PH3, AsH3, and SbH3, all of these molecules have one central atom surrounded by three hydrogen atoms and one lone pair of electrons. This gives them a trigonal pyramidal shape.

4. However, the bond angle decreases from NH3 to SbH3. This is because the size of the central atom increases down the group in the periodic table (from N to P to As to Sb). As the size of the atom increases, the bond pair - lone pair repulsion decreases, which results in a decrease in the bond angle.

5. Therefore, the bond angles of NH3, PH3, AsH3, and SbH3 are in the order of NH3 PH3 AsH3 SbH3.
