Question

Which of the following is a covalent compound?

Copper (sulfate), Water, Copper, Magnesium Oxide

Answer 1

Water

Step-by-step explanation:

A covalent compound is a compound formed by two or more elements that share covalent bonds, they are often formed when two non-metals react together and form a compound, for example Hydrogen and Oxygen creating water, and they are called covalent compounds because the bond that forms the compounds is created because of the share of the electrons by the nuclei.

Answer 2

Water is a covalent compound.

Step-by-step explanation:

covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.

Example:

Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).

Properties:

1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.

2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

3. Covalent compounds have lower melting and boiling points.
