Can somebody explain to me how hydrogenation is linked to margarine? I understand the mechanism and the chemistry bit, its just these wordy questions like what is it used for where I lose marks!

Using hydrogenation, you can harden polyunsaturated vegetable oils, since the hydrogenation affects how the oil hardens.
The two pics below should help.
Does anyone know where I can find some sort of map of the organic reactions? Something where like alkenes -hydrogenation-> alkanes, primary alcohols -distil oxidation-> aldehydes etc?
Ocr January 2010 question 4b: why does it say 'using your knowledge of group 7 elements, complete the electron configuration of bromine'? How is the electron configuration of group 7 elements any different to others?

Yeah,they do that all the time.It's only 1 mark,it's just testing your abilitu to write out the orbitals of elements.
Also for disadvantage of chlorine,I would think saying they form chlorinated hydrocarbons which are carcinogenic, would have been a better answer.

Can someone explain how to suggest the formula of sodium chlorate(VII). Can you explain the stages to figuring it out? Thank

Is the answer NACLO with a +4 charge overall?

It's NaClO4

I think it's because in this case Cl is 1+ and O4 is 4x-2 = -8. -8+1= -7 (VII)

Alkenes are hydrated into alkanes, not hydrogenated some sort of flowchart would be useful, is this a resource anyone has?

Okay well that is something i didn't know tell me more? Sorry for correcting you, was trying to help
tell me more? Sorry for correcting you, was trying to help How do u know if a carbon structure is primary secondary or tertiary?

Is it an electrophilic addition reaction?

No, it's just a addition reaction.

look at whats around the carbocation
general pattern: if carbocation is at the end of chain its primary.
if theres two alkyl groups surrounding it s secondary.
if theres three alkyl groups surrounding then its tertiary.
