Ionisation within body

Use the Henderson Hasselbach eq.

I have written that alcohol will not be ionised in physiological compartments but I am not sure as to why this is the case.

You have written where ? On an exam paper ? If so then who gives a s^*t ? You have done the exam. If not then why haven't they taught you this ? I learned all this stuff in 1st year.

For example?

Weak acids or bases are those whose ionisation is pH dependent. For weak acids, as the pH increases, dissociation increases. Duodenum would have higher pH than stomach and therefore weak acids (COOH) would dissociate in a more alkali environment.

For example a NH2 group becomes NH3+ within stomach (ph of 2) and CO2H becomes COO- at a ph of 6 in duodenum but why?

Either you're pulling my leg or Bath don't seem to make sure their students have an adequate grasp of basic chemistry as this is GCSE chemistry stuff. NH2 group becomes NH3+ in the stomach because of the H+ ions floating about. NH2 + H+ => NH3. See if you can work the other one out.
I will not answer questions like this in the future. It is googleable at the least and you should already have an understanding about acids and bases by now.

At bath we do organic chemistry
