Hello,
I am a little ocnfused, this is not homework Qs, but as Im writing up my practical, something has come into my mind. I have tried to use the internet, but teh answers are very confusing.
I'm sorry in advance if this is a silly Qs.
So when we oxidise ethanol into ethanal, we started off with sodium dichromate , to which we added sulphuric acid. We cooled teh solution in ice water until it was <10C.
why did we cool it??Then we added 0.5cm3 of ethanol and continued to monitor the mixture in the ice water, and tehre was an increase in tempereature.
Why was this??I probably should have asked my lecturer but I didnt really think of it then.
The below are homework Qs.Explain how different quanitities of Na2Cr2O7.H2O and different reaction conditions allow different organic products formed. Density of ethanol = 0.70g cm-3.I have no idea how to go about answering this Qs, even a lottel guidance to direct me in the right way will help lots.
Why is ethanoic acid higher strength acid than ethanal?Is this something to do with the hydrogen bonding and/or boiling point?
Thank you
