Consider the structure of Ephedrine, a dietary supplement now banned by the U.S. Food and Drug Administration. Ephedrine is an example of an organic compound, which we will study in more detail in Chapter 14. For the labeled atoms below, write their expected shape or geometry in the blanks. Compare your answers with those at the back of the book.

Chapter 12, Problem 1VC, Consider the structure of Ephedrine, a dietary supplement now banned by the U.S. Food and Drug

Expert Solution
To determine
The concept connection behind the visual image.

Explanation of Solution

Trigonal planar- The labeled carbon atom in ephedrine has three surrounding regions. All three regions are bond pairs. Therefore, the molecular shape around the labeled atom is trigonal planar.

Angular- The labeled oxygen atom in ephedrine has four surrounding regions. Two regions are lone pairs and other two regions are bond pairs. Therefore, the molecular shape around the labeled atom is angular.

Trigonal pyramidal- The labeled nitrogen atom in ephedrine has four surrounding regions...
