Organic Molecules Worksheet Review Answer Key
This comprehensive review of organic molecules is designed to help students master the key concepts and principles of organic chemistry. By working through this review, students will gain a deeper understanding of the structure, properties, and reactions of organic molecules.
Section 1: Organic Molecules Basics
- What is an organic molecule?
- An organic molecule is a type of molecule that contains carbon and hydrogen atoms, and may also contain other elements such as oxygen, nitrogen, and sulfur.
- What are the main components of an organic molecule?
- Carbon skeleton: the framework of carbon atoms that makes up the molecule
- Functional groups: specific groups of atoms that are attached to the carbon skeleton and determine the molecule’s properties and reactivity
- What is the difference between a saturated and unsaturated organic molecule?
- Saturated: contains only single bonds between carbon atoms
- Unsaturated: contains one or more multiple bonds (double or triple bonds) between carbon atoms
Section 2: Functional Groups
- What is a functional group?
- A functional group is a specific group of atoms that is attached to the carbon skeleton of an organic molecule and determines its properties and reactivity.
- What are some common functional groups?
- Hydroxyl (-OH)
- Carboxyl (-COOH)
- Amino (-NH2)
- Aldehyde (-CHO)
- Ketone (-CO-)
- How do functional groups affect the properties of an organic molecule?
- Functional groups can affect the molecule’s polarity, solubility, and reactivity
Section 3: Isomers
- What are isomers?
- Isomers are molecules that have the same molecular formula but differ in the arrangement of their atoms.
- What are the different types of isomers?
- Structural isomers: differ in the arrangement of their atoms
- Stereoisomers: differ in the arrangement of their atoms in space
- How are isomers formed?
- Isomers can be formed through the rotation of bonds or the replacement of atoms
Section 4: Reaction Mechanisms
- What is a reaction mechanism?
- A reaction mechanism is a step-by-step description of how a chemical reaction occurs.
- What are the main types of reaction mechanisms?
- Substitution reactions
- Elimination reactions
- Addition reactions
- Rearrangement reactions
- How do reaction mechanisms occur?
- Reaction mechanisms involve the breaking and forming of bonds between atoms
Section 5: Organic Molecules in Living Organisms
- What role do organic molecules play in living organisms?
- Organic molecules are the building blocks of living organisms and are essential for many biological processes.
- What are some examples of organic molecules found in living organisms?
- Carbohydrates (sugars, starches)
- Proteins (amino acids)
- Fats and oils (lipids)
- DNA and RNA (nucleic acids)
- How are organic molecules used by living organisms?
- Organic molecules are used for energy production, growth and repair, and the transmission of genetic information.
