Consider the following reaction: ethanal andhydrogen cyanide combine to form acetal cynohydrin Does this mean that as soon as the 2 solutions are poredinto the same beaker all of the reactants immediatelychange to the product?(Your answer should be 1-3 paragraphs

Q 13.54: Predict the expected organik productis) for the following reaction. Select all that apply. HI (excess) tert-butanol methanol iodomethane D tert-butyl iodide

Write a complete reaction mechanism using CORRECT nucleophile for the following substitution reaction; CI OCH3 i) Nucleophilic substitution 1 (SN1). ii) Nucleophilic substitution 2 (SN2).

46. The Strength of Nucleophile: Which one is the strongest nucleophile? OH (B) 0-CH, -CH, (D) O (C) O (A) O (D) O (B)

Can this be solved in fewer and more clear steps?

Please anwer my quetion fast and be carfulle

How was the last step resolved, please clarify.

4. Protonation of alcohol A and subsequent loss of water, produces the intermediate B. CH3 CH; CH, CH, — с — сH, CH, CH;CH, - C- CH, CH; | OH A B (a) (i) Name alcohol A. (11) What type of species is intermediate B? (iii) Draw the structures of the two alkenes which can be formed from species B by removal of a proton. Label as C the alkene which shows geometrical isomerism. (b) The intermediate B is readily attacked by nucleophiles such as water. What is the essential feature of a nucleophile? (c) State what final colour you would see if alcohol A were warmed with acidified potassium dichromate(VI). Explain your answer. Colour Explanation . (ii) Draw two structural isomers of alcohol A which form branched chain ketones when heated with acidified potassium dichromate(VI), but which could not form alkene C on dehydration.
