paper 2 Flashcards
how does flue gas desulphurisation work
calcium carbonate mixed with water to form alkali slurry
this is sprayed of flue gases
neutralisation
caco3 + so2 —-> caso3 + co2
what does fractional distillation separate
alkanes yeet
what is thermal crackig
high temp
high pressure
forms lots of alkenes
how would rate lf nucleophilic substitution change if its was f instead of cl
c-f bond is more strong
harder to break
slower rate
in nucleophilic elimination what does the oh act as
a base
what are the conditions required to turn a alkyl hydrogen sulphate into an alcohol
water and warm gently
unknown compound when reacted with sodium creates fizzing and gas produced with squeaky pop
alcohol
why is kcn a bad reagent
its toxic
how do u reduce a ketone and whats it called
u need NaBH4 and basically a H- ion forms as well as an H+
its nucleophilic addition
how do u form a soap
triglyceride +3 naoh —> glycerol and rcoo-na+
soponification
how do u form a biofuel
triglyceride + methanol(koh catalyst) —-> glycerol + ester (bifuel)
what are the colours of potassium dichromate
orange to green
whats the name of the polymer with an NHC=O group and whats it used as
a polyamide
used as kevlar / bullet broof vest
describe three challenges of making recyclable plastic
challenging to isolate the polymers
costs alot toncollect and sort
can get contaminated
why does inbreeding cause mutations
small gene pool
inbreeding depression
icreased chance of homozygous recessive genotype being expressed
