4.1 What is a hydrocarbon?
A compound of hydrogen and carbon only
4.2 How do you represent an alkene and alkane using the general formula?
Alkene: CnH2n Alkane: CnH2n+2
4.2 How do you represent an Organic compound using display formula.
Shows how all the atoms are arranged and all the bonds between . Search up for example
4.2 How do you represent an Organic compound using Structural formula.
Shows the arrangement of atoms carbon by carbon , with the hydrogens attached and functional groups.
4.2 How do you represent an Organic compound using molecular formula.
The actual number of atoms of each element in a molecule.
4.2 How do you represent an Organic compound using emperical formula.
1) Use the usual empirical formula method. 2) It is the simplest whole number ratio of atoms of each element in a compound
4.3 What is a homologous series ?
1) A group of compounds that can all be represented by the same general formula. 2) Contain same functional group so members often act in similar ways.
4.3 What is a functional group?
1) a group of atoms that determine how a compound typically react.
4.3 What is an isomerism?
Compounds with the same molecular formula but different structural formula.
4.4 How can you name organic Compounds?
1) count num of carbon atoms - this gives the stem. 1 = Meth 2 = Eth 3= Prop 4 = But 5 = Pent 6 = Hex 2) Find the functional group - if it has a double bond - ene or if it had an OH molecule, it would be -ol 3) Number the carbon chain so that the functional group has the lowest number 4) if theres more than one functional group , use di-(2), tri-(3),tetra(4) before suffix
