Q

Why is carbon so special

A
  • four electrons in its outer shells

23
Q

What is a molecular formula

A
  • shows the number and type of atoms of each element present in a molecule
24
What is the emperical formula
* simplest whole number ration of the atoms of each element present in a compound
25
What is the general formula
* simplest algebraic formal for any memeber of a homologous series
26
What is the general formula of alkanes
CnH2n+2
27
What is the general formula of alkenes
CnH2n
28
What is the general formula of alcohols
* CnH2n+1OH
29
What is the general formula of carboxylic acids
* CnH2n+1COOH
30
Whatt is the general formula of ketones
CnH2nO
31
What is a displayed formula
* shows the relative positioning of all of the atoms in a molecule and the bonds between them
32
What is a structural formula
* uses the smallest amoint of detail necessaru to show the arrangement of atoms in a molecule and groups bonded together
33
What is a skeletal formula
* simplified organic formula remove all of the carbon and hydrogen from carbon chain * remove any bond to hydrogen bonds * line represents a single bond * intersection of two lines represent a carbon atom * end of line represents a CH3 group
34
What is the formula for benzene
C6H6
35
What are structural isomers
* compounds with same molecular formula but different structural formulas
36
What happens with isomers with the same functioal group
* can usually be placed different positions along carbon chains * but remember that the formula can look the same when you flip the molecule
37
What happnes with isomers with different functional groups
* two molecules containing different functional groups can contain the same molecular formula * like aldehydes and ketons with the same number of carbon atoms
38
What is a covalent bond
* defined as a shared pair of electrons between two atoms
39
What is homolytic fission
* each of the bonded atoms take one of the shared pair of electrons from the bond * each atom now has a single unpaired electron
40
What is a radical
* an atom of groups of atoms with an unpaired electron
41
What is heterolytic fission
* one of the bonded atoms take both of the electrons from the bonds * te atom take both electrons becomes a negative ion * atom not taking the electrons become a positive ion
42
What are curly arrows
* used to show the movement of electron pairs when bonds are being broken or made
43
What is an addition reaction
* two reactants join together to fform one product * eg in an unsatruated alkene breaking of the double bond to form single saturated compound
44
What is a substitution reaction
* an atom or group of atoms replaced by a different atom or group of atoms
45
What is an elimination reaction
* involved the removal of a small molecule from a larger one * one reactant molecule froms two products usually
