I will try. Since organics cover a lot of content, I may not be able to do all three. I'll try to get aldehydes and ketones done if possible. :smile:

:smile:

Thanks!
I'd be waiting!

Aldehydes and Ketones notes are up. :smile:

:smile:

Let me know if there are mistakes, especially in the equations. May have balanced something wrong while rushing.

Thank you so much!!! I want to ask you, how did you practice solving questions about finding pH, because I am not that confident with it and I need to practice some (other than past papers)

For unit 4, is Gibbs Free Energy part of the specification, it's mentioned in the textbook but not in the specification? :redface:

No, it isn't.

The hydride ion H- is a strong reducing agent, a good nucleophile and a strong base. Which of the following changes could NOT be bought about by the ion. A)CH3CHO to CH3CH2OH
B) C2H5BR to C2H6
C) CH2=CH2 to C2H6
D) CH3COOH to CH3COO-
can someone help me with this question please(its unit 5)

hey i know this is a unit 5 thread but is anybody doing unit 4 tomorrow (ial)

So sorry I couldn't answer this, I got locked out of my account because I forgot my password! I hope the paper was alright. :smile:

15 cm3 of a gaseous hydrocarbon requires 90 cm3 of oxygen for completecombustion, both volumes being measured at 15􀁱C and 1 atm. The formula of thehydrocarbon is

A C4H6
B C4H8
C C4H10
D impossible to calculate without knowing the molar volume of gases underthese conditions.

Guys how do you do this? Please help

D) CH3COOH to CH3COO-
can someone help me with this question please(its unit 5)

A - Aldehyde is reduced to an alcohol by H- as its a strong reducing agent
B - acts as a good nucleophile (C2H5Br form C2H5+ carbocation)
D - It's accepted a proton if it's a strong base

It therefore has to be C, as it is undergoing hydrogenation

Can somebody please explain this question to me please?

I think it should be B if you look at the ionic equation of oxidation of Fe2+ to Fe3+.
Which paper is this from?
