? No, it has 0.93 Pauling compared to chlorine's 3.16 and argon's 3.2/undefined.

Again I'm losing the easiest fecking marks... With this sort of progress medicine will be out my reach :frown:

Was there a question about the highest current or something like that ?

Don't worry, I put argon - not sure if this is right, as some sources say it's 3.2, some say it's undefined...

Was that smile supposed to creep me out? Because it kinda did, especially because of the way you said 'hmmm..' So suspiciously :innocent:

For drawing the fully displayed formula for the functional group isomer of propene i drew three carbon atoms in a triangle :'h

RIGHT HELP ME ASAPP pleaseeee.. FOR THE 95% question i calculated the mass needed for 95% total, like i never worked out 5% of 550 and then added it on for 100%

I did the rest of the process correctly, though, do you think ill lose all the marks or just one for ECF???? honestly

I counted from the opposite direction so people who put 3,5 dichloro, 3,5 dimethyl hexane were equally correct as it doesn't matter which side you count from :smile:

It should have been 2,4 dichloro 2,3 dimethyl hexane.
Yes, technically they're the same but under IUPAC rules, minimum amount of numbers must be used when naming molecules

What did you guys think for the bond angle in the H202 molecule? I guessed 120 because it looked like it was 120. Found paper fine tbh apart for couple of 1/2 mark questions

Yea wasn't to sure put 128 since it had highest abundance

It's right so long as you drew displayed formula for cyclopropane - don't worry, they always say ignore bond angles.

Displayed formula is drawing I out fully with all the bonds right? At leat that's what my teachers said?

The numbers should be the lowest possible
