No, it was a trick as there were two carboxylic acid groups but only enough NaOH to react with one of them generating 1 mole of water per mole of Dioic acid.
Sneaky question

MCQ which I thought would catch a lot of people out, the most acidic in aqueous solution question between 4 different functional grouped compounds.

Answer was actually the acyl chloride because it reacts with the water to form HCl which is a strong acid, but it's a sneaky question and I imagine people put the carboxylic acid.

You have them the complete wrong way round there

How many marks would you lose if you got it the wrong way round

How did you do for the mlutiple choices question and asking about which one is the most acidic in water? I got D (acly chlorid+ water= carboxlic acid +HCl)

Butan-1-ol + [O] --> Butanoic acid and Water, using acidified potassium dichromate and under reflux

Butan-1-ol + [O] --> Butanal and water, using acidified potassium dichromate and distillation technique

that's what I put and then I drew the structures in displayed formula

you'll need 2 [o] for the formation of carboxylic acid

What were the names of the molecules which had to be named?

I put:
hex-3enol (apparently it has to be hex-3-en-1-ol)
3-methylphenol

3-methylphenol

If i recall correctly, it wasn't a benzene ring, it was just a normal cyclohexane ring. I put 3-methylcyclohexanol

Ok so according to past papers if your explanation is perfect then you lose 1 mark i your explanantion is averge but you got the compound wrong then you lose 2 marks so its not really that much an i think you'll be fine

3 methyl cyclohexan-1-ol and no there was no phenol there

I have a question to do with the way grades will be given this year. As there are no course work this year, will the total grade boundaries be much lower. This given to the fact that the course work system was broken, in the sense that most people had on there course work A-B. So students who got an U overall, had the similair grade in there course work as a student who got an A overall. Just wondering what everyone else thinks
