stick to the guidelines:
-in individual steps, state in general the preconditions for the occurrence of the mechanism that is stated (why SN2 and not SN1,E1,E2 etc.)
- if it is possible to give a review of other possible directions at the beginning of the reaction, whereby other by-products are formed, comment on possible competitive reactions
- in the case of resonant structures, they should be drawn and commented on
- comment on the stability of carbocations
1.)explain the mechanism and suggest the emergence of
by-products in both tasks
1st reaction - write the name of the carbocation and some resonant
structures that include both rings
- explain whether the nuclei on the structure below are aromatic,
antiaromatic, non-aromatic
2. reaction - explain the origin of the main and
by-product
