Section 1 of 7Alkenes

Alkenes alkene
  • Alkenes alkene Alkenes Alkene structure All alkenes contain a double carbon bond, which is shown as two lines between two of the carbon atoms i.e
Pent-2−ene, c
  • Pent-2−ene, c pent-2−ene, C H has the C=C between the 2 and 3 carbon atoms
In pent-3−ene
  • In pent-3−ene In pent-3−ene the C=C bond is between the 3 and 4 carbon atoms from the left

Section 4 of 7Alcohols

Oxygen
  • Oxygen is not required for ethanol to be produced by fermentation
Alcohols undergo
  • Alcohols undergo Alcohols undergo combustion to form carbon dioxide and water The complete combustion of ethanol is as follows: CH CH OH + 3O → 2CO + 3H O3 2 2 2 2 Worked Example Write a balanced symbol equation for the complete combustion of methanol
Write the
  • Write the Write the unbalanced equation CH OH + O → CO + H O 2
Balance carbon
  • Balance carbon Balance carbon 1 carbon on each side Already balanced CH OH + O → CO + H O 3
Balance hydrogen
  • Balance hydrogen Balance hydrogen 4 hydrogen atoms in CH OH So, 2H O needed CH OH + O → CO + 2H O 4
