**Question 2**  
*Points: 4*

As two molecules come closer together, the attraction between them increases to a maximum limit. Any closer and the molecules will repel each other because

- ○ a covalent bond is formed
- ○ the probability of charge asymmetry lessens
- ○ the electrons repel each other
- ○ the nuclei interact

**Explanation:**

This question explores the concept of molecular attraction and repulsion. When molecules approach each other, their potential energy changes due to electromagnetic interactions. Initially, attractive forces dominate, but when molecules get too close, repulsive forces become significant. The primary reason for this repulsion is the interaction between electrons of the approaching molecules, as they repel each other due to negative charge.

Expert Solution
Step 1

The nuclear force is powerfully attractive between nucleons at distances of about 1 femtometre (fm, or 1.0 × 10−15 metres), but it rapidly decreases to insignificance at distances beyond about 2.5 fm. At distances less than 0.7 fm, the nuclear force becomes repulsive.
