How many units of unsaturations does a compound with the formula C30H50Br2 have? Show your work. You may wish to review Section 7.2 in McMurry.

12.Use of KMnO, to effect oxidative cleave of the alkene J, C3H16, yields two fragments, one of which is butanoic acid and the other a ketone, Q. When J reacts with one molar equivalent of H-Cl, the alkyl halide K, C3H17CI, is formed. What are the structures of J, J, and Q? Write all the reactions, and show your reasoning.

1. An experimental technique called ¹3C-Nuclear Magnetic Resonance Spectroscopy allows chemists to tell how many different kinds of carbon there are in a molecule and whether carbons are primary (1°), secondary (2°), tertiary (3°), or quaternary (4°). Give dash (Kekule) structures (i.e., use lines for electron pair bonds) for the following compounds having a molecular formula C6H12. Also, on each structure, identify carbons as 1º, 2º, 3º, 4º; tell how many different kinds of C's there are; and designate which C's are equivalent. a) A compound having only single bonds and only secondary carbons. b) A compound having only single bonds and primary, secondary, and tertiary carbons. c) A compound having only single bonds and only primary, secondary, and quaternary carbons. d) A compound having only single bonds and primary, secondary, tertiary, and quaternary carbons.

What is a molecule that fits these three criteria: It should have a molar mass between 180 and 280 g/mol, contain a substituted cyclohexane like e. g. 5,6-dihydroxy-bicyclo[2.2.2]octane-2-carboxylic acid methyl ester, and be optically active.

Compound A (C6H14) forms three different monochlorides by photochemical chlorination. One of these monochlorides is inert to E2 elimination. The other two monochlorides produce the same alkene B (C6H12) when heated with potassium tert-butoxide in tert-butyl alcohol.Identify compound A, the three monochlorides, and alkene B.

This is an isomer of C4H10O, and it’s not an alcohol. What could the structure be, and what are the degrees of unsaturation? Which peaks would correspond with which carbons?

12) Draw the open form of the structure C6H12 according to the following reaction. 13) Name the following molecules. (It should be noted that E or Z)

What is the degree of unsaturation and structure for C8H5NO2 ?

Chiral compounds have a so-called asymmetric carbon atom in the molecular structure, and are opticalactive. Study the following organic molecule containing two −? − ? – groups (thiol) andwhich is a medicine against various types of metal poisoning, including against arsenic, mercury and lead: Image   Based on this skeletal structure, judge whether this molecule is chiral. Give reasons for your answer.Suggest an IUPAC name for the molecule that takes into account all the given functional groups.
