Match the following physical and chemical properties with octane, C 8 H 18 found in gasoline, or magnesium sulfate, MgSO 4 also called Epsom salts: a. contains only covalent bonds

All right. Hi everyone. So this question is asking us which of the following contains only covalent bonds. Sodium fluoride naf found in toothpaste or hexane C six H 14 widely used as a solvent option A says sodium fluoride. Option B says hexane option C says both and option D says neither. Now to understand the answer to this question, let's go ahead and differentiate between two different types of chemical bonds. We can differentiate between ionic bonds and covalent bonds recall that an ionic bond involves an exchange of electrons in between two atoms. In other words, one is going to receive electrons and the other is going to be giving them away. So ionic bonds. All right, normally seen between a cat ion or a substance with a positive charge, usually a metal as well as an anion or a substance with a negative charge. Usually a non metal poly atomic ions can count as well. But the idea here is that in an ionic bond electrons are exchanged, which results in different charges between both species. Now, on the other hand, covalent bonding discusses a sharing of electrons between two atoms. Now, covalent bonds are characteristic of nonmetals, right. So two nonmetals are more likely to participate in a covalent bond in which electrons are being shared between them as opposed to being traded. So now let's compare the structures of sodium fluoride and hexane. Sodium fluoride is composed of one sodium Adam and one atom of flooring. Now here recalled medals are excellent cat ions or are very common cat ions. So that would be exactly what's happening in this case because sodium is the cat on and fluoride is the anion because fluorine is referred to as fluoride to specify that it has a negative charge in this compound. So because of this, we can see that sodium fluoride is an ionic compound and therefore does not contain any covalent bonds. Now, on the other hand, hexane is a hydrocarbon, it is a molecule composed only of carbon and hydrogen, both of which are non metals. So because of this hexane can only be composed of covalent fonts because it is only composed of non metals that are capable of sharing electrons in between them as opposed to exchanging. And there you have it, this shows that hexane is the compound that contains only covalent bonds, which means that my answer is going to be option B in the multiple choice and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful

Textbook Question

Match the following physical and chemical properties with octane, C₈H₁₈ found in gasoline, or magnesium sulfate, MgSO₄ also called Epsom salts:
a. contains only covalent bonds

Verified step by step guidance

Step 1: Understand the nature of the bonds in the two compounds. Octane (C₈H₁₈) is a hydrocarbon, meaning it is composed entirely of carbon (C) and hydrogen (H) atoms. These atoms are connected by covalent bonds, which involve the sharing of electrons between atoms.

Step 2: Analyze magnesium sulfate (MgSO₄). This compound consists of magnesium (Mg), sulfur (S), and oxygen (O). Magnesium forms ionic bonds with the sulfate ion (SO₄²⁻), while within the sulfate ion, sulfur and oxygen are connected by covalent bonds.

Step 3: Compare the bonding in the two compounds. Octane contains only covalent bonds, as all the bonds between carbon and hydrogen atoms are covalent. In contrast, magnesium sulfate contains both ionic and covalent bonds.

Step 4: Match the property 'contains only covalent bonds' to the correct compound. Based on the analysis, this property applies to octane (C₈H₁₈).

Step 5: Conclude that magnesium sulfate (MgSO₄) does not match this property because it contains ionic bonds in addition to covalent bonds.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Covalent Bonds

Covalent bonds are a type of chemical bond where two atoms share one or more pairs of electrons. This sharing allows each atom to attain the electron configuration of a noble gas, leading to greater stability. In organic compounds like octane (C₈H₁₈), covalent bonds are predominant, as they consist of carbon and hydrogen atoms bonded together.

Octane (C₈H₁₈)

Octane is a hydrocarbon and a key component of gasoline, consisting of eight carbon atoms and eighteen hydrogen atoms. It is a non-polar molecule that primarily exhibits covalent bonding. Understanding octane's structure is essential for recognizing its physical and chemical properties, such as its flammability and energy content.

Magnesium Sulfate (MgSO₄)

Magnesium sulfate, commonly known as Epsom salts, is an ionic compound composed of magnesium ions (Mg²⁺) and sulfate ions (SO₄²⁻). Unlike octane, it contains ionic bonds, which result from the electrostatic attraction between positively and negatively charged ions. This distinction is crucial when comparing the bonding types and properties of different substances.
