Potential Energy Curve for Hydrogen Molecule || Chemical Bonding L-2 || Class 11th || JEE || NEET
Chemistry Mam in Equilibrium・2 minutes read
Understanding the potential energy curve for hydrogen molecule formation is essential for exams like JE and NEET, where the force of attraction between hydrogen atoms dominates over repulsion to create a bond at a minimum potential energy point called bond length.
Insights
- Understanding the potential energy curve is vital for exams like JE and NEET, where the force of attraction surpassing repulsion leads to bond formation.
- The bond length is the distance between the nuclei after bond formation, a critical point where potential energy is minimized and forces of attraction and repulsion are balanced.

Hydrogen Molecule Formation: Potential Energy Curve
- Understanding the potential energy curve for hydrogen molecule formation is crucial for exams like JE and NEET.
- Initially, two hydrogen atoms are far apart with no force acting between them.
- As the atoms approach each other, forces of attraction and repulsion come into play due to opposite charges.
- The formula for force is derived from the formula for potential energy, which is k q1 q2 / r.
- At a specific point, the force of attraction dominates over the force of repulsion, leading to bond formation.
- Bond formation occurs when potential energy is at a minimum and forces of attraction and repulsion are equal.
- The distance from the center of one nucleus to the center of the other nucleus after bond formation is called bond length.
