IDO BEGINNING ON MONDAY 8TH FEBRUARY, 2021. DEASE COMPLETE YOUR TUTORIAL SHEET FOR DISCUSSIONS IN YOUR TUTORIAL SESSIONS NB: Tutorial sheets will be handed out weekly, each one containing a few questions covering material from the previous week's lectures. The material on the sheets will be discussed at the tutorial sessions. Please revise your lecture notes on a weekly basis, do the necessary background reading and attempt the tutorial sheets. 1) a) Draw curved arrow(s) to show how aniline is converted to its resonance structure A and how resonance structure A is converted to resonance structure B. Draw the resonance structure C. > B C Aniline b) The following resonance structures are used to describe the molecule diazomethane. It is a bright yellow, volatile, toxic, explosive and useful gas. H,C=N=N: + H,C-N=N: Indicate the presence of any formal charges on these resonance structures by placing + and/or - signs above the appropriate atoms. Show all such charges in both structures.…

how does the ring open? can you add more steps?
