IB DP Chemistry: SL复习笔记10.2.7 Alkenes - Hydration
Hydration of Alkenes When alkenes are treated with steam at 300 oC, a pressure of 60 atmospheres and sulfuric acid (H2SO4) or phosphoric acid (H3PO4) catalyst, the water is added across the double ...
IB DP Chemistry: SL复习笔记10.2.6 Alkenes - Hydrohalogenation
Hydrohalogenation of Alkenes Alkenes will react readily with hydrogen halides such as HCl and HBr to produce halogenoalkanes This reaction is known as hydrohalogenation It is also an electrophilic...
IB DP Chemistry: SL复习笔记10.2.5 Alkenes - Halogenation
Halogenation of Alkenes The reaction between alkenes and halogens is known as halogenation It is an example of an electrophilic addition where an electrophile ('electron seeker') joins onto to a do...
IB DP Chemistry: SL复习笔记10.2.4 Alkenes - Hydrogenation
Hydrogenation of Alkenes Alkenes are very useful compounds as they can undergo many types of reactions They can therefore be used as starting molecules when making new compounds The reaction betwee...
IB DP Chemistry: SL复习笔记10.2.3 Alkenes - Reactivity
Reactivity of Alkenes Alkenes are hydrocarbons containing a carbon-carbon double bond The atoms around the carbon-carbon double bond adopt a planar arrangement and the bond angle is 120o The bondin...
IB DP Chemistry: SL复习笔记10.2.2 Alkanes - Halogenation
Halogenation of Alkanes Free-radical substitution of alkanes Alkanes can undergo free-radical substitution in which a hydrogen atom gets substituted by a halogen (chlorine/bromine) Since alkanes a...
IB DP Chemistry: SL复习笔记10.2.1 Alkanes - Combustion
Unreactive Alkanes Strength of C-H bonds Alkanes consist of carbon and hydrogen atoms which are bonded together by single bonds Unless a lot of heat is supplied, it is difficult to break these stro...
IB DP Chemistry: SL复习笔记10.1.12 Benzene
Benzene Kekulé structure for benzene Kekulé suggested that benzene was a hexagon with three double bonds It was therefore equivalent to three ethene molecules Problems with Kekulé’s structure for b...
