Draw the electrophillic addition reaction between alkene and bromine
draw the Elimination of Halogenoalkanes with ethanolic
hydroxide ions
draw Acid catalysed elimination mechanism: alcohols to alkenes
draw Acid catalysed addition mechanism for hydration of ethene
Draw Nucleophilic substitution
outline the free radical sub reaction between alkanes with bromide
STEP ONE Initiation
Br2 to 2Br . Essential condition: UV light
CH3CH3 + Br. to HBr + CH3CH2
. STEP TWO Propagation
CH3CH2
. + Br2 to CH3CH2Br + Br. STEP THREE Termination
CH3CH2
. + Br. to CH3CH2Br
CH3CH2
. + CH3CH2
. to CH3CH2CH2CH3
draw nucleophilic sub with ammonia
Draw a nucleophilic addition reaction
Draw a nucleophilic addition elimination reaction
Draw a electrophilic substitution reaction
state the conditions for nucleophilic substitution
ethanolic, (unless using OH when it can be aq) warm (and ammonia must be at pressure)
State the conditions for elimination
heat, ethanol slovent and conc KOH
What causes a major and minor product
The major product is formed from the most stable carbocation intermediate (more carbons attached therefore more positive inductive effect) and the minor product is formed from the least stable carbocation intermediate.
