b. Can one of the possible molecular formulas contain a nitrogen atom?

Verified step by step guidance

1. Step 1: Understand the context of the problem. The question is asking if a molecular formula can include a nitrogen atom. This implies that we are considering the possible elements that can be part of a molecular formula.
2. Step 2: Recall the common elements found in organic compounds. Typically, organic molecules are composed of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), and halogens (such as fluorine, chlorine, bromine, and iodine).
3. Step 3: Consider the role of nitrogen in organic chemistry. Nitrogen is a key element in many organic compounds, such as amines, amides, and nitro compounds. It is also a fundamental component of amino acids and nucleic acids.
4. Step 4: Evaluate the possibility of including nitrogen in a molecular formula. Since nitrogen is a common element in organic chemistry, it is indeed possible for a molecular formula to contain a nitrogen atom.
5. Step 5: Conclude that, based on the typical elements found in organic compounds and the role of nitrogen, a molecular formula can certainly include a nitrogen atom.

Key Concepts

Molecular Formula

A molecular formula represents the number and types of atoms in a molecule. It is expressed using chemical symbols and subscripts, indicating how many of each atom are present. For example, C6H12O6 denotes a molecule with six carbon, twelve hydrogen, and six oxygen atoms. Understanding molecular formulas is crucial for determining the composition of compounds and predicting their properties.

Nitrogen in Organic Compounds

Nitrogen is a common element in organic chemistry, often found in amines, amides, and other functional groups. Its presence can significantly affect the chemical behavior and reactivity of a compound. For instance, nitrogen can participate in hydrogen bonding, influencing solubility and boiling points. Recognizing how nitrogen integrates into molecular structures is essential for analyzing organic compounds.

Valency and Bonding

Valency refers to the ability of an atom to bond with other atoms, determined by the number of electrons in its outer shell. Nitrogen, with a valency of three, typically forms three covalent bonds, allowing it to connect with various elements, including carbon and hydrogen. Understanding valency is fundamental for predicting how atoms combine to form stable molecules, particularly in organic chemistry.
