Draw a structural formula for each of the following compounds that have a complex substituent. First interpret the name of the parent compound, then interpret the name of the substituent given in parentheses. By convention, the carbon atom of the substituent attached to the parent chain or ring is designated C1.  a. 4-(1,1-Dimethylethyl)-4-octanol b. 3-Chloro-2-(1-hydroxyethyl)-6-nitrophenol c. 3-(2-Fluoro-2-propenyl)-5-hepten-2-one d. 4-(1-Methylethyl)-5-methyl-3-hexenal

Draw the structure of the expected organic product(s) formed in the following reactions including correct stereochemistry. If the product is racemic, write racemic or draw both isomers. Assume all reagents listed are present in excess unless otherwise noted. If no reaction occurs, state "no reaction".

Organic chemistry student Peter is tasked with synthesizing (R)-3-ethylpentan-2-ol. Using his knowledge of alkene reactions, he runs a hydroboration/oxidation reaction on 3-ethylpent-2-ene. Upon isolation, Peter runs an optical rotation experiment to determine the enantiopurity of his alcohol. Which of the following statements would be MOST correct regarding the optical rotation of his synthetic sample (Note: the specific rotation of (S)-3-ethylpentan-2-ol is +28.2°). O [x] of the sample will be +28.2° O [x] of the sample will be 0° O [x] of the sample will be between 0° and -28.2° O [a] of the sample will be -28.2° O [x] of the sample will be between 0° and +28.2°

identity and draw structural isomers and/ or stereoisomers where possible. For each isomer, clearly explain what type of isomerism is being shown and how it arises. i) CH3CH(CH3)CH2CH2Cl
