CIE A Level Chemistry复习笔记3.2.5 Chemical Reactivity of Alkanes
Unreactivity of 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...
CIE A Level Chemistry复习笔记3.2.4 Cracking of Alkanes
Obtaining Useful Compounds by Cracking Crude oil Crude oil is a mixture of hydrocarbons containing alkanes, cycloalkanes and arenes (compounds with a benzene ring) The crude oil is extracted from t...
CIE A Level Chemistry复习笔记3.2.3 Free Radical Substitution
Free Radical Substitution Mechanism Alkanes can undergo free-radical substitution in which a hydrogen atom gets substituted by a halogen (chlorine/bromine) Ultraviolet light (sunlight) is needed fo...
CIE A Level Chemistry复习笔记3.2.2 Combustion & Free Radical Substitution of Alkanes
Combustion & Free Radical Substitution of Alkanes Alkanes are combusted (burnt) on a large scale for their use as fuels They also react in free-radical substitution reactions to form more react...
CIE A Level Chemistry复习笔记3.2.1 Alkanes
Production of Alkanes: Hydrogenation & Cracking Alkanes are hydrocarbons that can be produced by the addition reaction of hydrogen to an alkene or by cracking of longer alkane chains Production...
