C11- intro to organic chemistry Flashcards
how many bonds does carbon have
4
what is a functional group
a group of atoms responsible for the characteristic reactions of a compound
whats a homologous series
a group of compounds with the same functional group
name the six types of formulae
molecular, empirical, displayed, structural, skeletal and general
what is a molecular formula
the actual number of atoms of each element in a compound
what is a displayed formula
all atoms and all covalent bonds are shown
what is a structural formula
shows arrangement of atoms wothout showijg the bonds
what does it mean is a group is in brackets in the structural formlula
it is not part of the main carbon chain
what is an empirical formula
the simplest ratio of elements in a compound
what is not shown in the skeletal formula
carbon and hydrogen atoms
what is a general formula
type of empirical formlula that represents all compounds in a homologous series
what is the general formula for alkanes
CnH2+2
whats general formula for alkenes
CnH2n
whats general formula for alcohols
CnH2+10H
what does X nornally represent
a halogen
what dies the syllable ane mean
only single bonds

what are structural isomers
compounds with same molecular formula but different arrangement if atoms
name three tyoes of structural isomerism
chain
position
functional group
positional isomers
compounds with same functional geoup at diff locations on the carbon chain
functional group isomers
compounds woth same molecular formula but diff functional groups
chain isomers
compounds eith different ways if arranging carbon atoms in the longest chain
what are stereoisomers
compounds with same molecular and structural formula but a different 3D arrangement in space
two tyoes of stereoisomers
E and Z optical isomers
what is an aliphatic compound and what letter represents it?
hydrocarbon molecules with a single double or triple bond, R
what is an aromatic compound
organic compounds whoch contain a delocalised ring of electrins
example of aromatic compound
benzene
