Problem 612 - 1,001 GED Practice Questions For Dummies

Question

Which is the name of the compound whose formula is \(\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6\) ? (A) chlorophyll (B) propane gas (C) glucose (D) cellulose

Step-by-Step Solution

Answer

The name of the compound with the formula \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\) is glucose (option C).

Step 1: Analyze Option A - Chlorophyll

Chlorophyll is a green pigment found in plants, responsible for photosynthesis. The chemical formula for chlorophyll is \(\mathrm{C}_{55}\mathrm{H}_{72}\mathrm{O}_{5}\mathrm{N}_{4}\mathrm{Mg}\). This does not match the given formula \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\), so we can eliminate this option.

Step 2: Analyze Option B - Propane Gas

Propane gas is a hydrocarbon and commonly used as fuel. Its chemical formula is \(\mathrm{C}_3\mathrm{H}_8\). This formula does not match the given formula \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\), so we can eliminate this option as well.

Step 3: Analyze Option C - Glucose

Glucose is a simple sugar and an important carbohydrate in biology. The chemical formula for glucose is \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\). This formula matches the given formula. Therefore, this could be the correct answer.

Step 4: Analyze Option D - Cellulose

Cellulose is an organic polymer and the main component of plant cell walls. Cellulose has a general formula of \((\mathrm{C}_6\mathrm{H}_{10}\mathrm{O}_5)_n\), where \(n\) represents the number of glucose units. The general formula for cellulose is not the same as the given formula \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\), so we can eliminate this option.

Step 5: Choose the correct option

Among the four options, only glucose has a chemical formula of \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\). Therefore, the name of the compound with the given formula is glucose, which corresponds to option (C).

Key Concepts

Compound Naming

Understanding the naming of compounds is essential in chemistry. It is the unique identifier that allows chemists to communicate about specific chemicals. The International Union of Pure and Applied Chemistry (IUPAC) has established rules for the systematic naming of compounds, ensuring that each compound has a distinct name. For example, the compound with the formula \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\) is named glucose according to IUPAC rules. This skill is vital for students preparing for their General Educational Development (GED) tests as it lays the foundational knowledge required in the chemistry section.

When looking at a chemical formula, identifying the compound involves recognizing the structure and composition of the molecule. In the context of the exercise, knowing the various functions and sources of biomolecules helps to further eliminate incorrect options, leading to correct identification. An online platform offering educational content must therefore ensure that examples and practice questions reinforce these rules for compound naming, aiding students in committing them to memory through application and repetition.

Chemical Formulas

Chemical formulas convey crucial information about the elements that compose a compound and their respective quantities. For instance, the molecular formula \(\mathrm{C}_6\mathrm{H}_{12}\mathrm{O}_6\) represents a molecule with 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Understanding how to read and interpret these formulas is a key skill in organic chemistry, which deals with carbon-containing compounds.

For learners accessing GED study material, recognizing and differentiating between simple formulas, like that of propane gas \(\mathrm{C}_3\mathrm{H}_8\), and more complex carbohydrates, such as glucose, is essential. In addition, mastering the interpretation of chemical formulas contributes to a student's ability to understand the structure and function of biomolecules and complements their study of biology concepts on the GED.

GED Study Material

The GED exam is an alternative to the traditional high school diploma and covers four main subjects: Mathematical Reasoning, Reasoning Through Language Arts, Science, and Social Studies. In the Science section, students will encounter a variety of chemistry-related content, which includes compound naming, understanding chemical formulas, and a basic overview of biomolecules.

In order to cater to these students, educational platforms should provide practice questions that are aligned with the GED curriculum, ensuring that the content is not only accurate but also appropriate for the level of understanding required for the exam. Tools such as step-by-step solutions help to demystify complex topics, and further explanations on these key concepts reinforce learning and retention, setting students up for success on their GED exams.

Biomolecules

Biomolecules are the essential compounds that constitute the building blocks of life. This includes carbohydrates like glucose, proteins, lipids, and nucleic acids. Each type of biomolecule plays a specific role in biological systems, for example, carbohydrates serve as energy sources, with glucose being a primary form of energy in living organisms.

To enhance a student's understanding of biomolecules, educational content should explore not just their chemical structure, as indicated in their formulas, but also their function and importance in living systems. Interactive and applied learning opportunities, such as analyzing cellular processes or comparing the structures of different carbohydrates, can greatly improve the comprehension of these vital organic chemistry concepts. For students utilizing GED study materials, relating biomolecules to real-life functions aids in making the subject matter tangible and easier to grasp.
