Alkenes and Alcohols
-
Test for unsaturation:
This forms 1,2-dibromoethane "ethane" because the double bond is broken in order to add Br, so a single bonded carbon pair remains
This reaction decolorization the reddish-brown colour of bromine making it colourless, hence, the unsaturated hydrocarbon is present. - known as halogenation
Ethene is added to aqueous bromine. They undergo an addition reaction where the Br gets added to ethene

Down the series, the number of electrons and surface are increases hence Van der Waals force increases

Alcohols have a general formula of CnH2n+1OH. Similar to Alkanes CnH2n+2 but in alcohols there is one less H because an OH is added hence it is H2n+1
