Answer

### B. Carbon tetrachloride

Explanation

## Step1: Identify the nature of bonds in each compound### Covalent bonds are typically formed between nonmetals. We need to analyze each compound to determine if it consists of nonmetals.- Sodium hydride (NaH): Sodium (metal) and hydrogen (nonmetal) form an ionic bond.- Carbon tetrachloride : Carbon (nonmetal) and chlorine (nonmetal) form covalent bonds.- Magnesium chloride : Magnesium (metal) and chlorine (nonmetal) form an ionic bond.- Sodium hydroxide (NaOH): Sodium (metal) and hydroxide (OH, nonmetal) form an ionic bond.## Step2: Select the compounds with covalent bonds### Based on the analysis, only carbon tetrachloride has covalent bonds.#
