Part 1. • Draw the structures of the three C5H12 structural isomers below. • • Make models of the molecules to be sure that you understand which of the carbons are identical by symmetry. Fill in the table, using NMR spectra 1a-c. Structure IUPAC Name Number of C's # of Types of C's (Skeletal) Labe 1° 2° 3° 4° 1° Corr.* NMR(s) 2° 3° 4° Tot *"Corr."

Draw structures for the two fragment ions of highest mass from the following molecule.

Give detailed Solution with explanation needed of all options ...don't give Handwritten answer..

Which c. ..se structures shows how the pictured molecule will look after it is flipped over horizontally, as illustrated? он flip OH H H. OH он H. ..l OH none of these но Note: Only check the boxes of structures that correspond to a single horizontal flip of the original structure. Ignore structures that have been rotated or flipped multiple times or in other ways.

Question 1: Aromaticity a. Draw a fully labelled MO energy diagram for each (match clearly). b. Determine criteria for the following molecules that aligns with the criteria for aromaticity. I will NOT accept anything outside the list done in class – NOTHING YOU HEARD FROM SOMEONE OTHER THAN ME, READ OR SAW ONLINE. List clearly for each molecule the way we did in class. c. Determine if the molecule are aromatic or antiaromatic based on your list. d. Of the two molecules, which would be most reactive in an electrophilic addition? Why?

Between these 2 compounds, which one will be (R) and which one is (S) configuration? Please draw to explain your answer in detailed..

None
