homologous series definition
a group of organic compounds that have the same functional group, share a general formula, and show a graduation in physical properties
trends in physical properties
- INCREASE in mp/bp, density & viscosity
- DECREASE in flammability
Alkane general formula
CnH2n+n
alkane saturated/unsaturated hydrocarbon + why
Saturated, contains only C-C single bonds
Alkane reactions + what is produced/needed
COMBUSTION: water and carbon dioxide
SUBSTITUTION of Halogens (group17) in presence of sunlight
alkene general formula
CnH2n
alkene saturated/unsaturated hydrocarbon + why
Unsaturated, contains C-C double bonds (C=C)
alcohol general formula
CnH2n+1OH
alcohol functional group
-OH
Carboxylic acids general formula
CnH2n+1COOH
number of lines for each molecule=
number of electrons needed for stable electronic configuration

hydrocarbon meaning
an organic compound that contains only carbon and hydrogen elements
petroleum is also known as
crude oil, a mixture of hydrocarbons
common forms of fossil fuels
crude oil & natural gas
natural gas consists of mainly
methane gas
why is natural gas considered non-renewable
as limited amount of natural gas & cannot be replaced quickly enough to keep up with our rate of use
a process is environmentally sustainable if
has ability to be maintained at a steady level without exhausting natural resources or causing severe ecological damage
how is CO2 produced and why harmful
produced from burning of fossil fuels contributes to global warming
how sulfur dioxide produced and why harmful
produced from burning of fossil fuels forms acid rain which corrodes bridges and buildings
