Topic 6 Flashcards
Stereoisomer
-same structural formula
-diff arrangement in space
Fractional distillation
-Diff boiling point
-due to diff chain length
Free radical substitution
homiletic bond fission, free radicals
Alcohol bp
-oh groups form hydrogen bond
-more E needed
Cracking
-release short chain alkane and alkene
-demand increased
Isomers
-branched chains
-low sa/less point of contact
-weaker London forces so less e needed
catalytic converter
2NO+2CO->N2+2CO2
cynide reaction
useful as increase carbon chain length
heating
-increase reaction rate
-sealed so products don’t escape
Rate of hydrolysis
-ethanol as solvent
-silver nitrate
-measure time taken for precipitate
-same temp and volume of halogen
How can small UV result in a big product
Radical recycled each time
UV and hydrogen
High bond enthalpy for hydrogen so radical not formed as UV not strong enough
Incineration
HCl produced
Toxic
Use of ethanol
It increases solubility of halogenoalkane
How are halides present in halogenoalkanes
Hydrolysis of halogenoalkane results in heterolytic bond fission
