Question
**Question 3:**

Determine whether the following statements are true or false. Completely fill in the circle in front of your chosen answer.

(a) A compound with a plane of symmetry must be achiral.

- (a) ○ True
- (a) ○ False

(b) A compound with two or more stereocenters must be chiral.

- (b) ○ True
- (b) ○ False

**Explanation:**

For statement (a), a compound that has a plane of symmetry means it is superimposable on its mirror image and is thus achiral. Therefore, the statement is true.

For statement (b), while many compounds with two or more stereocenters are chiral, it is not always the case. Some compounds, such as meso compounds, can be achiral despite having multiple stereocenters due to an internal plane of symmetry. Hence, the statement is false.

Expert Solution
Step 1: Chiral carbon:

The sp3 hybridized carbon atom that is attached to the four different types of atoms or groups is known as chiral carbon or stereocenter. A molecule that is superimposable on its mirror image is said to be achiral. A molecule that is not superimposable on its mirror image is said to be chiral.
