Study Notes
Bidentate Ligands
- Bidentate ligands are ligands that bind to a central metal ion through two donor atoms.
- Example: Ethylenediamine (en)
Nylon 6,6 Polymer
- Monomers:
- Adipic acid
- Hexamethylenediamine
- Structure: (Describe the structure of the polymer and monomers)
Molar Mass Calculation
- Given:
- Mass of solute = 0.822 g
- Volume of water = 0.3 dm³ = 0.3 L
- Osmotic pressure = 0.196 atm
- Temperature = 298 K
- Calculate molar mass using the osmotic pressure formula.
Nucleotide
- Nucleotides are organic molecules that serve as the building blocks of DNA and RNA.
Polyacrylonitrile (PAN) Preparation
- Write the reaction for the preparation of PAN.
Difference between Double Salt and Coordinate Compounds
-
Double Salt:
- A crystalline compound which consists of two or more salts.
- Each salt retains its own chemical properties.
- Separates on crystallization into different components.
-
Coordinate Compound:
- A compound formed by the combination of a central metal ion and surrounding ligands.
- Ligands are bonded to the central metal ion through coordinate covalent bonds.
- Ligands have lone pairs for donation.
- Example: (Provide an example of both a double salt and a coordinate compound)
Applications of Coordinate Compounds
- Provide two applications of coordinate compounds.
