A study of medicines (such as aspirin) their development, chemistry, synthesis and illustrating some
of the features of the pharmaceutical industry. The chemical ideas in this module are:
Phenols, carboxylic acids, esters, carbonyl compounds;
Acid­base reactions;
Medicine manufacture and testing;
IR spectroscopy and mass spectroscopy.
Chemical Ideas Topics: 6.4, 6.5, 7.5, 8.1, 13.2, 13.3, 13.4, 13.5, 13.7, 15.…read more

Simple Molecule (covalent)
o Low melting and boiling points
Only have to overcome weak intermolecular bonds ­ not the covalent
bonds)
o Sometimes solid ­ usually liquid or gas
Liquid and gases have the weakest intermolecular bonds
o Solid doesn't conduct electricity
No free electrons to carry the charge
o Liquid doesn't conduct electricity
Same as above
o Solubility depends on how polarized the molecule is
If polar, water can pull apart the molecule (due to the electrostatic
attractions…read more

Organic Reactions
Homologous Series
We need to remember the organic compounds from As, the homologous series, their
general formula and how to name them
Alkanes
o General formula
CnH2n+2
o Functional group
N/A (Strictly speaking C-C and C-H bonds are- but they're so unreactive that
they're not normally considered as functional groups)
o Example
2-methylpentane
Alkenes
o General formula
CnH2
o Functional group
C=C
o Example
3-methylbut-1-ene
Alcohols
o General formula
CnH2n+1OGH
o Functional group
O-H
o Example
Butan-1-ol…read more

We also need to be aware of the organic reactions ­ from temperature, reagents,
experimental method etc...

Aria Fard

This doesn't have nearly enough accreditation! These are the most comprehensive notes I have found on the internet. Very impressed, thank you

Michael

Thanks Aria :) Good luck!

THANKS MICHAEL YOU STUD X

Masood Jamil

These notes are great, thank you! Do you have notes for unit 5 (F335)

Joshua Drabble


Excellent notes, thank you

Joshua Drabble


Excellent notes, thank you

Joshua Drabble


Excellent notes, thank you

Michael

Thanks Guys - Masood, unfortunately I don't. I find the best revision for that exam is just to read revision books over and over again, with the occasional poster here and there,

Eleanor

Brilliant notes! They helped me so much, can't thank you enough.

Jia

why is this link not working anymore? please can you upload all your notes again...

Sasha

hi, your links aren't working for any of your revision notes for a2 chemistry. can you try to upload it again please?

sanzzy

the link is not working, please could you try and fix it? thanks

nirjala

hi your link isnt working , can we still find these notes somewhere ? :)
