also i think we should be good with a line graph

thx the lord (i almost died when i saw one of the early sols using column graph, didn't even think of it lol just defaulted to line)

 

[lucas10champ]

bar is better but line should also be fine

 

[nonya2000]

i think its continuous since it represents an increase in atomic number, hence line graph is fine

 

[BionicMango]

It’s not continuous but we can treat the trend like it is.
Atomic number is discrete.

We can't have random additions of atomic numbers across all real numbers. wouldn't make sense. Although I think personally that it should be fine using a line since it generally is used when we view trends such as the ones present in bp of homologous series. idk for sure if there's a penalty

This exam had a lot of niche stuff tbh, they’re probably doing this since the syllabus is going extinct soon, I saw it happen last year as well with physics for example

yup with a 2 marker qualitative circuits question

what if i did line of best fit

you'll be fine

bro I fkn just ended up with 4 x’s and no trendline after erasing my bar chart fk I’m cooked aren’t I

they didnt tell us we had to draw a line. infact a line probably invalidates the graph anyway. a plot is the most appropriate

I may have named my substance for the last question 3-methyl-2-butene (despite drawing the correct structure) am I going to lose marks? It did say only determine the structure

I think I have seen criterias for similar qs have “small nomenclature error” like a misplaced number being acceptable, but it’s up to the markers at this stage.

Praying rn lol - buts its last question so I assume its going to be marked at B6 level so no room for error.

i did the exact same thing but its only 1 mark what can u do
