4A.2 Different types of formulae Flashcards
what are the different types of formulae
- displayed
- structural
- skeletal
- molecular
- empirical
what a displayed formula show
a diagram that shows every atm and every bond
what is a structural formula show
it is a simplified version of the displayed formula where it would show (unambiguously) how atoms are joined together. where it would group each atom joined to a particular carbon atom
what is a skeletal formula show
it shows a zigzag line that would represent the carbon bonds, every change of direction and every ending means there is a carbon atom(with as many carbons as needed). it would start with CH3 and end with CH3
what is a molecular formula show
shows the real number of each atom in a molecule, they can show more than one compound unlike the structural, displayed, and the skeletal formula
what does the empirical formula show
it shows the number of each atom in the simplest whole-number ratio
