Textbook Question
Chapter 1, Problem 12ALQ
As part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the cars passing through this intersection for a 24-hour period during a weekday. The graph of hourly traffic looks like this.
- At what lime(s) does the highest number of cars pass through the intersection?
- At what time(s) does the lowest number of cars pass through the intersection?
- Briefly describe the trend in numbers of cars over the course of the day.

If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used.
