Reaction of Alkane

Reaction of Alkane
Reactions
- Source
- fractional distilation crude oil
- catalytic cracking crude oil
- Combustion
- complete
- sufficient O2
- Carbon dioxide +water vapour
- non luminous flame
- incomplete
- insufficient O2
- Carbon monoxide + soot + unburnt hydrocarbons + water vapour
- luminous flame
- Uses
- Fuel
- Catalytic Cracking
- Alkane(large)--(cracking)-->smaller alkene+smaller alkane/hydrogen
- Hydrogen produced
- fuel
- reducing agent
- haber process
- uses
- convert large hydrocarbon into smaller hydrocarbon
- less flammable to more flamable
- fuel
- reducing agent
- haber process
- conditions
- 450°C, SiO2/broken porous pot or Al2O3
- Free Radical substitution
- Free radicles
- chlorine..etc
- alkanes react with chlorine (under UV) chloro alkanes + hydrogen chloride
- condition
- UV light
- random
- no. /sequence atoms substituted cannot be predicted
Structure
- Bonds
- C-C
- Saturated
- Contain no C=C
- cannot undergo addition rxn
- Formula
- C2 H2n+2
Chemical properties
- unreactive generally
- alkenes compared soot lesser
- C% alkenes than less C%
