any clarification, feel free to discuss!!
disclaimer: these are not the "model" answers, just what we believe to be the best explanation we are able to give. we are human too and there could be mistakes as well :)

overall, very standard P3 which went according to plan. its a good day. we will continue to prepare for P1 which is the last impt hurdle. do not look down on this final 15%. I have talked about the importance of P1 and its tremendous ability to help u jump 1-2 grades if done properly.
similar to P3 it can be trained as well which means the effort u put in will definitely show results. will be releasing the P1 package to my students shortly.

simple organic synthesis. some students may struggle a bit w the final step which is an intramolecular freidal crafts. but those who are familiar w it will find it easy

testing of cell diagram, rmb to put ur standard conditions. students also needed to be able to draw the link between delta G and Eocell

mole concept. simple manipulation. the only thing students might struggle with at this pt is probably time management.

traditional physical property of transition elements. shdnt pose any issues

simple electrophilic subn mechanism. this is a freidal craft type of rxn. if students can recognise it, it shdnt pose much issues

simple dimerisation. rmb to discuss both the covalent and dative bonds. simple chem eqm qn as well

periodicity was also expected to come out. can possibly talk about the bond length increases down the group as well hence less effective orbital overlap. but jus decided to focus a bit more on the empty p orbital since the current discussion was regarding lewis acidity

expected atomic structure concepts to come out.quite standard qns

nothing much here. rmb to show wedge and dash to show 3D structure

simple mechanisms. i chose to remove the proton from the organic molecule instead of NH3 because i think NH3 is likely to be more basic / (less acidic) than the one i have chosen. probably both accepted.

standard VSEPR qn. need to briefly explain what is VSEPR because qn ask to use VSEPR theory. besides its 3 marks

simple energetics qns. common trick is for students to forget to manipulate the value of delta H or delta S to same magnitude

deductive. there shd be one other possible structure of F that will fit the data, which is the side chain on the next adjacent carbon below what i have drawn.

we expected reaction kinetics to be tested in P3 as it was noticeably missing in P2. very standard boltzmann diagram

we also exposed our students to aldol reactions before. so even though it is a novel qn, they shd find it very familiar.

Simple EA mechanism.
Not much novel qns this yr in P3 which shd be a huge relief to students :)

Rmb to write ur balanced eqn. We lazy here. But relatively easy E°cell manipulation to decide on feasibility.

Simple manipulation as long as u are not careless. Hope we didn't make any mistakes here as we did it in a rush.

The ideal gas graph was harder to explain. We nv teach this concept in sch for quite long alr. Usually teach the btm deviation only for the attractive force and ignore the repulsive side. But it's ok if u don know. 2 marks only

Standard TM colour. All of our students shd get the full credit here pls

Very standard ratio counting. And understanding of ring activating vs deactivating groups

Likely to have some variation in ans for the FRS mechanism part.
