C–C C=C –OH –COOH image
list general formula • alkanes • alkenes
• Cn H2n+2 • Cn H2n
define: homologous series in organic chemistry
a group of organic compounds that have the same general formula and share similar properties
name one ester
ethyl ethanoate
reactants used to make an ester
alcohol + carboxylic acid
structural formula • ethene • ethanol • propanoic acid
• CH2CH2 • CH3CH2OH • CH3CH2COOH
list 2 properties of alcohol
• soluable in water • neutral pH
word equation combustion of alcohol
alcohol + oxygen → carbon dioxide + water
describe reaction of alcohol with sodium
Acts very similarly to water and sodium, sodium will effervesce. However it is less vigorus.
list: 2 uses of ethanol
• alcohol production (the drug) • biofuel via fermentation
word equation producing ethyl ethanoate
ethanoic acid + ethanol → ethyl ethanoate + water
Are carboxylic acids weak or strong? Why?
weak, as they do not ionise completely
