Draw a structural formula of the S configuration of the compound shown below. CH3 CH;CHCHCN CH2NH2 • Use the wedge/hash bond tools to indicate stereochemistry where it exists. Include H atoms at chiral centers only. • If a group is achiral, do not use wedged or hashed bonds on it.

4. Draw both geometric isomers of 1-fluoro-2-methylbut-1-ene using skeletal formula. Clearly label the E and Z isomers. [

What is the relationship of these two structures?

Consider 1,2-dimethylcyclohexane.Q: Draw structures for the cis and trans isomers using a hexagon for the sixmembered ring.

5) Provide your own list of alkanes. They can not be the same structure but should all have the same number of carbons. (see the problem solving video for an example) Rank them in order of increasing melting point. You can not have the same example as someone else.

3.  How many kinds of H are there in the isomers of dimethylcyclopropane?

I need diagrams or more detailed representations of each structure 1. Glycolaldehyde (C₂HO₂) • Molecular Formula: C₂H₂O₂ Structural Formula: H-C(=O)-CH2-OH • Skeletal Formula: A straight chain with an aldehyde group (-CHO) at one end and a hydroxyl group (-OH) on the other. . Condensed Formula: HOCH CHO 2. Benzaldehyde (CHO) • Molecular Formula: CHO . Structural Formula: ![Benzene ring]-CH=O • Skeletal Formula: A hexagonal ring representing benzene with an aldehyde group (-CHO) attached. • Condensed Formula: C H CHO 3. Valeraldehyde (CHO) Molecular Formula: CH₁O • Structural Formula: CH,-(CH,),-CHO • Skeletal Formula: A chain of five carbons with an aldehyde group (-CHO) at the end. Condensed Formula: CH3(CH2) CHO •
