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.

1. Using only reactions we have discussed in class, fill in the missing intermediates(two), regents(two), and the fill product in the following multi step synthesis. Assume all reactions proceed too quickly for rearrangements to take place/

Which of the following methods can be used to synthesize 2-methyl-1-hexene, shown below, with no formation of isomeric by-products? ОН H2SO4 A) heat H2SO4 OH B) heat Ci (CH3);CO Na* + D) H2C=P(C,H5);

Substitution and elimination: predict the product Maximum allowed tries per question: Unlimited (7) Draw the major organic product of the reaction. Follow this procedure: determine whether the reaction conditions are acidic or basic; identify the most nucleophilic/basic atom, the electrophilic atom, and the leaving group; predict whether elimination or substitution will occur; and then draw the product. Indicate the stereochemistry at every stereocenter with a single wedged (up), hashed (down), or wavy (a mixture of up and down; either) bond.
