In each of the following pairs, which is more covalent and why?
LiCl and LiBr

Explanation

To determine which compound is more covalent between LiCl (lithium chloride) and LiBr (lithium bromide), we can follow these steps:

### Step 1: Identify the ions in each compound
- LiCl consists of Li⁺ (lithium cation) and Cl⁻ (chloride anion).
- LiBr consists of Li⁺ (lithium cation) and Br⁻ (bromide anion).

### Step 2: Compare the sizes of the anions
- The size of the chloride ion (Cl⁻) is smaller than that of the bromide ion (Br⁻).
