Show all intermediates, (including any and all proton transfers) however it is not necessary to provide all resonance structures. Be sure to indicate where the labeled (¹80) oxygen is located throughout the mechanism and in the product or products. (The enrichment of the labeled oxygen as isotopically pure 180 does not affect the mechanism in any way other than that it allows identification of where the final position of that oxygen is). catalytic H₂SO4 علی 18 OH

For SN1 Explain if 3o ( tertiary) alkyl halides reacted (fastest or slowest) explain why. Be sure to explain if alkyl halides did not react or did react and why. 3o (tertiary) compounds listed are: 2-chloro-2-methylpropane (see picture) Base your explanations on the following considerations: the nature of leaving group, the effect of structure, steric hindrance and any other feature.

Please help me I don't understand this, its a simple mecahnism but im lost.
draw all 8 steps of the mechanism with arrows When acetic acid is treated with isotopically labeled water (180, shown in red) in the presence of a catalytic amount of acid, it is observed that the isotopic label becomes incorporated at both possible positions of acetic acid. Drawa mechanism that accounts for this observation. For the mechanism, draw the curved arrows as needed, Include lone pairs and charges in your answer. Do not draw out any hydrogen explicitly in your products. Do not use abbreviations such as Me or Ph. Do not attempt to draw the isotopic 180 in your product, they will be drawn in the pre-drawn structures to show the location but do not try and replicate the isotopic 180 in your structures.
