Joinomdm reaction mechanism doubt
so I was solving this problem in omdm... In omdm a mercurinium ion (non classical) formation takes place. My teacher said that we've to break this from the site where there's more cationic character, determined by inductive and NOT mesomeric.
Then in the image I've attached, why do we break from the site where phenyl is attached. doesn't it exhibit -I effect? It is better cuz of resonance, but my teacher told we shouldnt look at that....

biomolecules
why is it so that manmose is written as D-(+)-Mannose, and gulose is written as D-(-)-Gulose. + aur - sochne mein problem horahi ha. mannose i think ki jitna clockwise rotate hoga utna hi anticlock bcz of its arrangement, but aisa bhi nahi ha

optical isomerism - relation problem
i had a doubt in this problem. now i know that a pos passes through the compounds III and IV. don't they have like a pseudo chiral centre? Like R,r,S and R,s,S (small r and s representing pseudo chiral centre config.)...
I've been taught that RrS and RsS are diastereomers. Then why'd they be identical? Unless I have got it wrong entirely......
