Name each molecule. 2. Use the molecules in the reactions 1 through 9 highlighted in red to determine the product. 3. Draw the line/angle or skeletal structure of eachmolecule. 4. Use the alkyne below to predict the products 1- 9.

Draw a skeletal (bond-line) structure of (R)-2,2,3- trimethylhexane. Use a dash or wedge bond to indicate stereochemistry of substituents on asymmetric centers, where applicable.

Draw a tetrahedral representation of the (2S,4S) enantiomer of 2-bromo-4-chlorohexane. O Use the wedge/hash bond tools to indicate stereochemistry where it exists. • Show stereochemistry in a meso compound. [ ] در ? ChemDoodleⓇ

Draw a structural formula for 2-cyclopenten-1-ol. • Show stereochemistry only if given in the name. • If a group is achiral, do not use wedged or hashed bonds on it. • In cases where there is more than one answer, just draw one.

I know the answer is correct but I can’t figure out if C is tertiary ? It can’t be secondary because it has more than two carbons connected to the +C

Draw the skeletal line-bond structure of (R)-4-isopropoxyoctane. Include a dash or wedge bond to indicate stereochemistry of substituents.
