SRRY MANHahaha i know but can u do these 2 questions? if u can please explain them. Thanks
InshAllah!Thanks buddy
same to you
well honestly speaking its not that bad compared to how hard the Paper 1 is
i usually get around 30 now a days i used to get 20 before it all becaus eof practice
but then coming to the gt they are too damn high for paper 1
you should score more than 30 to be on the safe side for paper 1
and as for paper 3 try just losing a mark or 2 or none cause paper 3 are very easy and they will safe you
InshAllah we all will get Good grades

Regarding Q28.
Key phrase in the question is "excess NaOH was used"
NaOH + SO3 --> NaHSO3 ---(1)
As there is excess NaOH, the HSO3- (acid) will further react.
NaHSO3+ NaOH --> Na2SO4 + H2O --(2)
Combine eqn (1) and (2), you will have the overall equation.
2NaOH + SO3 -->Na2SO4 + H2O
Q28. Tertiary alcohols can be oxidized by strong oxidizing agents (which is out of the syllabus), reason why they question use the phrase "not oxidized by mild oxidizing agents" is simply to reassure students that we are definitely talking about tertiary alcohols.
Q35 is as explained by ZaqZainab
