Question

name the following binary covalent compounds: 1. s₂o₆ 2. ccl₄ 3. p₂s₇ 4. bbr₃

Explanation:

Step1: Recall naming rules for binary covalent compounds

Name the first - element using the element name. Name the second element with an - ide ending. Use prefixes to indicate the number of atoms of each element (mono - for 1, di - for 2, tri - for 3, etc., but mono - is usually not used for the first element).

Step2: Name $S_2O_6$

The first element is sulfur. There are 2 sulfur atoms, so we use "disulfur". The second element is oxygen. There are 6 oxygen atoms, so we use "hexoxide". The name is disulfur hexoxide.

Step3: Name $CCl_4$

The first element is carbon. There is 1 carbon atom (no prefix needed). The second element is chlorine. There are 4 chlorine atoms, so we use "tetrachloride". The name is carbon tetrachloride.

Step4: Name $P_2S_7$

The first element is phosphorus. There are 2 phosphorus atoms, so we use "diphosphorus". The second element is sulfur. There are 7 sulfur atoms, so we use "heptasulfide". The name is diphosphorus heptasulfide.

Step5: Name $BBr_3$

The first element is boron. There is 1 boron atom (no prefix needed). The second element is bromine. There are 3 bromine atoms, so we use "tribromide". The name is boron tribromide.

Answer:

1. Disulfur hexoxide
2. Carbon tetrachloride
3. Diphosphorus heptasulfide
4. Boron tribromide
