F1 Definitions Flashcards
Define empirical formula
The simplest, whole-number ratio of elements in a compound
Define the molecular formula
The actual number of atoms of each element in a molecule
Define the structural formula
The minimal detail for an unambiguous structure
Define the displayed formula
The relative placing of atoms and the bonds between them
What is a structural isomer
Same molecular formula , different structural formula
What is a chain isomers
A type of structural isomerism where the carbon skeleton is different
What is a position isomer?
An example of structural isomerism when functional groups are in different positions on the same carbon chain
What is functional isomerism
Same molecular formula with different functional groups
What is stereo isomerism? (Geometric isomerism)
Same molecular formula but atoms in a molecule have different arrangements in a space
Enthalpy change
Heat change at constant pressure
Hess’s Law
The enthalpy change of a reaction is independent of the route taken from reactants to products
Biofuel
A fuel produced from biological sources
Chlorine with water in bright sunlight
2Cl2 + 2H2O -> 4HCl + O2
