No offense. But I was highly amused. :D

hey guys, so this is given in one of my chem pdfs

prntscr.com/mkemjz

(the reactant is phenyl chrloride)

and then theres this

prntscr.com/mkemw1

why are the products in both of them involving Br, when Cl is the original halide? It must be a mistake right? But its been repeated twice so I asked just to be safe..

Q: How to identify hydrogen bonds and other non-covalent interactions from structure considerations?

Chemistry is governed by a wide range of interactions, from ionic and covalent bonding, or other types of strong interactions, towards weaker types of bonding, attraction, or repulsion, that typically occur between molecules. The latter are often referred to as chemical, molecular, or non-covalen...
