the molecule is called 3-chloro,6-methylheptane!
i honestly dont think i dropped a mark!!
only coz i owned biol last year though
 nooobs

that's wrong, "infraredismybitch"

it is 5-chloro-2-methylheptane

or the less correct version

2-methyl-5-chloroheptane

pwnt Tongue

What was the specific wording of the question again? I seem to remember that it asks for "a/the systematic name" for the molecule, not the correct IUPAC nomenclature. If you go strictly by IUPAC, then ethylamine would not be accepted as a correct name and heaps of people wouldn't get the mark for that question.

But I think they'll be lenient about it, past exams have accepted ethylamine ...so...?

ctrl-c ctrl-v ftw

edit: yeah seems a bit misleading, I'm actually asking about the acceptable naming for the second molecule, i.e. the tricky heptane, not the first one. Quite sure ethylamine is acceptable, but not so confident about strictness on '5-chloro-2-methylheptane' or variants.

[mhsstudent]

that was hard.

[Synesthetic]

I'm quite convinced now that the answer to 7)d) is H· - i.e. a free radical. Hopefully they won't be too strict with this - I hardly expect many people to write that down (I wrote H+, which was silly).

I need to post up:

Question 2 [for dilution]
Question 6 [for nomenclature]
Question 8 [by request]

[might not be able to finish it tonight, but we'll see how it goes]


all up (first post)
