Across
  1. 6. an ion that contains a positively charged carbon atom
  2. 8. first stage of radical substitution, a halogen molecule is broken into two radicals by homolytic fission
  3. 9. an addition reaction in alkenes in which a hydrogen is added across a double bond
  4. 12. process by which crude oil can be separated into fractions of alkanes with similar boiling points
  5. 14. final stage of radical substitution, two radicals collide and react to form a compound
  6. 15. isomers that have the same structural formula but a different arrangement of atoms in space
  7. 16. bond type present in alkanes, found in single covalent bonds, the direct overlap of s orbitals
Down
  1. 1. addition reaction in alkenes in which a halogen is added across a double bond, happens rapidly
  2. 2. formation of polymers from small repeating monomer units
  3. 3. reaction of alkenes in which they react with steam to form alcohols in the presence of a phosphoric acid catalyst
  4. 4. a species with an unpaired electron
  5. 5. intermolecular forces found between alkanes
  6. 7. second stage of radical substitution, a radical reacts with a compound to form another radical and another compoun
  7. 10. an atom/group of atoms that is attracted to an electron-rich centre and accepts an electron pair
  8. 11. mechanism for the reaction between alkanes and halogens, eg bromine
  9. 13. shape around each carbon atom in alkanes
