Arrange in decreasing polarity of bonds `SbH_(3),AsH_(3),PH_(3),NH_(3)`

Explanation

To arrange the compounds \(SbH_3\), \(AsH_3\), \(PH_3\), and \(NH_3\) in decreasing order of bond polarity, we can follow these steps:

### Step 1: Understand Electronegativity
The polarity of a bond is determined by the difference in electronegativity between the two atoms involved in the bond. The greater the difference, the more polar the bond.

### Step 2: Identify Electronegativity Values
We need to look up the electronegativity values for nitrogen (N), phosphorus (P), arsenic (As), and antimony (Sb):
- N: 3.04
