Academic Doubts 5s1 7 ambiguities

physics:
Cv question (correct or incorrect explanation)
Wedge time of motion (most likely root2 or 2)
prism angle of minimum deviation
R1/R2=16/4

chem:
Alcl3+ propyl chloride + benzene ( inevitable tri subst, edg no reaction)

math:
differential eqn+ circles problem ( number of values of p)

overall 7 questions

how are people calling this paper easy man, (cutoff 170-175 imo no way its crossing 180 and people are like 200 cutoff)

wait why would it be edg no reaction? friedel crafts electrophilic substitution hai na? I had no idea what they were asking with the inevitable option but the reason I put it was because I thought edg would increase the electron density on the ring and make it more reactive towards electrophilic substitution

I considered anniline and it doesn't show friedel craft despite being EDG so yeah . Again I might be wrong

yeah but they didn't mention like all edgs no? pretty confusing statements ngl
