Q 3(b) [50 Marks] Ozone is a 1,3-dipole, and ozonolysis (reaction of ozone and an alkene) has been used extensively in identification of organic structure, prior to development of modern spectroscopic techniques. (i) Draw the 1,2- and 1,3- canonical forms of ozone. (ii) Draw the molecular orbitals for a 1,3-dipole, and identify the HOMO and LUMO of ozone.
4. Draw structures corresponding to the following systematic names; a) 1-isopropyl-4-methylcyclohexene b) 3-butyl-2-heptene c) 4-methyl-1,2- hexadiene d) trans-3,3-dimethyl-4-propyl-1,5-octadiene e) (42)-2,4-diethyl-1,4-hexadiene f) 1.2-propadiene g) (32,5E) -2,6-dimethyl-1,3,5,7-octatetraene h) cis-2,2,5,5-tetramethyl-3-hexene i) Methylenecyclohexane, j) trans- 1,2 divinylcyclohexane
please explain fully. also I am confused why there are numbers in
with E and Z
(2.) Draw structures corresponding to the following names: a) (4E)-2,4-dimehyl-1,4-hexadiene b) Cis-3,3-dimethyl-4-propyl-1,5-octadiene c) 4-methyl-1,2-pentadiene d) (3E,5Z)-2,6-dimethyl-1,3,5,7-octatetraene e) 3-butyl-2-heptene f) Trans-2,2,5,5-tetramethyl-3-hexene
step after each product of the the structure 5. Consider the three reaction sequences below (a, b & e) and draw Stereochemistry in the products should be clearly indicated in your drawings when app your entire reaction sequence before you jump into any conclusions! Always make sure that the starting material and p reaction conditions! (24 points, 2 points each) icable Hints: Look very carefully at products, so that you are not adding or losing more of these atoms than...
