7- Organic Chemistry

• Polymer: A chain of the same molecule
• Functional Group of Alcohol: -OH
• Functional Group of Carboxylic Acids: C=OOH
• Functional Group of Esters: -COO
• Carboxylic acids can react with alcohols to form Esters. Through Esterification
• Reversible reaction mean it goes through partial ionisation. There a weak acid.
• Describe the Structure of DNA: Double Helix, Has 4 bases - neucleotides, two polymer chains.
