OMG CHEMISTRY UNIT 1 PAPER!!!!!!!!!!!!

[aniekan]

i jst wrt homolytic fission!

i wrote homolytic fission n condition is UV radiation!

Radiation ? probably radiation and light are equal/ similar --but it's UV light ----I was not too sure xD so i wrote Free radical homolytic fission xD

isn't it free radical substitution?.. ._.

Hahaha yeah I wrote that too that smaller fractions are more useful than heavier ones . I read in the text book right now that alkenes are obtained from the cracking of alkanes so that could have been one of the answers but I didnt write in the exam The second point I wrote was to obtain hydrogen

Lol Even i wrote that smaller chains are more useful...but then i wrote that they are more easy to recycle :/

No because it asked about step 1 not 2

That's correct : well I wrote cracking produce : Alkene which are used for making polymers and 2) cracking produce alkane used as feed stock for *reforming (which is wrong i guess) and making petrol (this is right) ---so my last answer is neither right nor wrong

i said they are cracked into smaller hydrocarbons because large ones are really volatile..and less flammable so they are less usefull

Volatile ? should be viscous.......

 

[shoaeb]

Less Volatile*****

 

[aniekan]

Less Volatile*****

yeah equally likely = less volatile=more viscous

They didnt tell us to draw lithium iodide... :/ The told us to draw the lithium ion and the iodine ion... :/​

Pretty sure they said to draw lithium iodide but showing full electron shell of lithium and only the valncy shell in iodide :s

that's what i thought but i failed xD i drew covalent bond for them xD--stupid me

ik..i was correcting what i wrote.

wht abt the ionization energy of hydrogen!?

 

[aniekan]

wht abt the ionization energy of hydrogen!?

it will move from ground state up

marks included.

only for A level I guess xD

 

[Lost_Life]

only for A level I guess xD

i dunno..i guess in June you get it all together..

Great xD but I hate it. I prefer the grade alone without the actual score

we all do prefer that xC
