Ethene reacts with steam in the presence of sulfuric acid. Which type of reaction is this?

13.2.1.1 homologous series

13.2.1.2 saturated and unsaturated

13.2.1.3 homolytic and heterolytic fission

13.2.1.4 free radical, initiation, propagation, termination (the use of arrows to show movement of single electrons is not required)

13.2.1.5 nucleophile, electrophile, nucleophilic, electrophilic

13.2.1.6 addition, substitution, elimination, hydrolysis, condensation

13.2.1.7 oxidation and reduction (in equations for organic redox reactions, the symbol [O] can be used to represent one atom of oxygen from an oxidising agent and the symbol [H] one atom of hydrogen from a reducing agent)

13.2.2.1 free-radical substitution

13.2.2.2 electrophilic addition

13.2.2.3 nucleophilic substitution

13.2.2.4 nucleophilic addition (in organic reaction mechanisms, the use of curly arrows to represent movement of electron pairs is expected; the arrow should begin at a bond or a lone pair of electrons)

14.2.1.1 elimination of HX from a halogenoalkane by ethanolic NaOH and heat

14.2.1.2 dehydration of an alcohol, by using a heated catalyst

14.2.1.3 cracking of a longer chain alkane

14.2.2.1.1 hydrogen in a hydrogenation reaction, and Pt/Ni catalyst and heat

14.2.2.1.2 steam, catalyst

14.2.2.1.3 a hydrogen halide, HX(g) at room temperature

14.2.2.1.4 a halogen,

14.2.2.2 the oxidation by cold dilute acidified to form the diol

14.2.2.3 the oxidation by hot concentrated acidified leading to the rupture of the carbon–carbon double bond and the identities of the subsequent products to determine the position of alkene linkages in larger molecules

14.2.2.4 addition polymerisation exemplified by the reactions of ethene and propene

14.2.3 describe the use of aqueous bromine to show the presence of a C=C bond

14.2.4 describe the mechanism of electrophilic addition in alkenes, using bromine / ethene and hydrogen bromide / propene as examples

14.2.5 describe and explain the inductive effects of alkyl groups on the stability of primary, secondary and tertiary cations formed during electrophilic addition (this should be used to explain Markovnikov addition)
