Guys please, does anyone know what happens when you forget to write the date down on extra paper that you use?? I remembered to write everything else, just completely forgot about the date!! I'm having a huge panic, almost half my answers were on that

I put ch3cooh + hno3 ---> h2o + ch3ch2coo- no2+
Is that right ????

There did have to be. That's why it was HOCH2COCH2CH(CH3)2

dw, the invigilators go through the papers in the end, to ensure everything (names, dates, numbers) are in place.

Yes, I got this and I believe it's correct! 😀

This was the answer to the last question.. (I got it wrong and drew it as a tertiary alcohol:/
The integration value of 6 with the CH3 included the one on the left..)
How many marks would I loose for tertiary alcohol? I'd imagine 1 for not mentioning it having to be primary or secondary, 1 for wrong product and 2 probably for an error in my working that showed a segment of R-C(CH3)2OH..
So most likely -3/4 what do you think?

Chemistry teachers looked at it and said it's relatively easy. Should be high grade boundaries.

for distinguishing between one compound and the acyl chloride i said use NaHCO3 and with the acyl chloride you get effervescence and no visible change with the other, is that correct?

i wrote just aqueous, id still get the mark right?
