Study Notes
Organic Molecules
- Organic molecules primarily contain carbon and hydrogen.
- Examples of organic molecules:
- Methane (CH4)
- Glucose (C6H12O6)
- Non-organic molecules:
- Carbon dioxide (CO2)
- Sodium chloride (NaCl)
- Water (H2O)
Hydrogen Count in Hydrocarbon Chains
- A hydrocarbon chain consisting of three carbon atoms (C--C--C) can hold a total of eight hydrogen atoms.
Hydrophilicity of Molecules
- Hydrophilic molecules attract water and can readily dissolve in it.
- Example of a completely hydrophilic molecule:
- Glucose (C6H12O6)
- Non-hydrophilic examples include:
- Hexane (C6H14)
- Decanol (C10H22O2)
Isomerism
- Isomers are compounds that have the same molecular formula but different structures.
- Two molecules with the same formula (C6H12O6) can exist as isomers.
- A molecule with the formula C5H10O5 cannot be an isomer of C6H12O6, as they have different compositions.
