Textbook Question

Draw structures for the following:
c. 2,2,3,3-tetramethyloxirane

Verified step by step guidance

Step 1: Understand the name of the compound. The name '2,2,3,3-tetramethyloxirane' indicates that the compound is an oxirane (a three-membered cyclic ether, also known as an epoxide) with four methyl groups attached to specific positions.

Step 2: Start by drawing the basic structure of oxirane. Oxirane is a three-membered ring containing two carbon atoms and one oxygen atom. Represent this as a triangle with one vertex being oxygen.

Step 3: Identify the positions for substituents. The numbering of the oxirane ring starts at one of the carbon atoms adjacent to the oxygen. Assign the numbers 1, 2, and 3 to the oxygen and the two carbon atoms, respectively.

Step 4: Add the substituents. According to the name, there are two methyl groups attached to carbon 2 and two methyl groups attached to carbon 3. Draw these methyl groups as branches extending from carbons 2 and 3.

Step 5: Verify the structure. Ensure that all atoms have the correct number of bonds (carbon should have four bonds, and oxygen should have two bonds). Confirm that the structure matches the IUPAC name '2,2,3,3-tetramethyloxirane'.

Key Concepts

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

Stereochemistry

Stereochemistry is the study of the spatial arrangement of atoms in molecules and how this affects their chemical behavior. In the case of 2,2,3,3-tetramethyloxirane, understanding stereochemistry is crucial for accurately drawing the structure, as the arrangement of substituents around the oxirane ring can lead to different isomers with distinct properties.

Functional Groups

Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. In this case, the oxirane (or epoxide) functional group is a three-membered cyclic ether, which is important for understanding the reactivity and properties of 2,2,3,3-tetramethyloxirane.

Nomenclature

Nomenclature in organic chemistry refers to the systematic naming of chemical compounds based on their structure and functional groups. The name 2,2,3,3-tetramethyloxirane indicates the presence of four methyl groups attached to the oxirane ring, and understanding this naming convention is essential for accurately interpreting and drawing the compound's structure.
