• Alkenes have double double carbon bond
• General formal for alkenes is CnH2n
• General formula for alkanes is CnH2n+2
• Hydrogenation is when two hydrogen atoms are added across the double bond which is then converted to a single bond - alkane.
• Hydration ethene is reacted with steam at high temperatures with the presence of a phosphoric catalyst to form alcohols.
• Alcohols react with sodium metal to form a solution of sodium aloxide with hydrogen given off
• Sodium reacts with alcohols to produce hydrogen
• Sodium reacts with water vigorously
• Esters made by reacting alcohols and carboxylic acids, with presence of a strong acid catalyst
