Introduction
• Hydrogen bond can be defined as the attractive force which binds hydrogen atom of one molecule with the electronegative atom (F, O or N) of another molecule.
Pre-Requisites:
Elements, periodic table, bonding, molecules
Activity:
Our DNA has hydrogen bonds in it. Water molecules combine together by hydrogen bonds.
Real Life Question:
How does DNA hold together?
