Alcohols are a group of compouds that contain an OH bond (an oxygen atom convently bonded to a hydrogen atom). OH group is an example of a functional group - a group of atoms responsible for the chemial properties of the compound. all alcohols act in similar ways.
the nameing system for alcohols is the same as alkanesonly instead of the -ane it's -anol. The first part of the name depends on the amount of carbons their are 1= meth 2=eth 3=prop 4=but (Monkeys Eat Pealed Bannanas)
The fromula of an alcohol is CnH2n+1OH eg C2H5OH (ethanol)
properties and uses of alcohols
- alcohols are flammable. they producing carbon dioxide and water.
- alcohols react with sodium to from hydrogen and alkoxides
- (only the first 3) can completely dissolve in water to from a neutral solution
- ethanol is in alcholic drinks
- as solvents as methanol, ethanol and propanol can all dissolve in subantces that water can't it is useful in the solvents industry eg perfumes and aftershave
- used to can thing clean and sterial using alcohol wipes
- can be used as fuel
carboxylic acids are a group of compounds that contain a -COOH (a carbon atom which a double bound to an oxygen atom and a single bond to another oxygen atom that is bonded to a hydrogen atom) functional group. in its sybol from you can tell if it is a carboxylic acid as there will be 2 oxygen atoms.
the name of all carboxylic acids end in -anoic acid.
properties and uses of carboxylic acids
- carboxylic acids react with carbonates to produce carbon dioxide and a salt ending in -anoate
- they can dissolve in water to form an acidic solution as it releases H+ ions which are responsable for making the solution acidic
- long chained carboxylic acids are used to creat soaps and detergents
- ethanoic acid is in vinegar
- carboxylic acid is in citric acid in some fruits
esters have a function group of -COO- a carbon atom that has a double bond with an oxygen atom and a single bond to another oxygen atom. esters form when an alcohol and a carboxylic acid react together with a by product of water.
all esters end in -oate. the first part of the name comes from the alcohol. and the secound from the carboxylic acid.
properties and uses of esters
- esters have a pleasant smell often sweet and fruity
- they are flammable
- esters don't mix well with water
- they do mixes with alcohols
- esters are toxic to humans
- esters are used in perfumes due to there aromas
- they are solvents for paint,ink and glue
- esters are in nail varnish remover
