Chem 219 Unit 5 Exam with Correct Solutions Generic formula for alcohols - Answer -R-OH phenol - Answer -hydroxy-substituted aromatic molecules (any compound with an -OH attached to a benzene ring) IUPAC system rules for naming organic alcohols - Answer -- organic alcohols are named by replacing the suffix of the parent chain of the molecule with the suffix -ol - The parent chain is numbered so as to give the hydroxyl group the lowest possible number. (examples: 1-propanol, and cyclohexan...

Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...

How does information flow? From DNA to RNA to protein What information is central to modern biotechnology? The use of methods to study and manipulate information about the central dogma. What is the exception to the central dogma? The transcription of RNA into DNA using reverse transcriptase. How does the cycle of the central dogma work? Instructions of DNA are transcribed onto messenger RNA. The ribosomes are able to read the genetic information inscribed on a strange of the ...

Alcohol - Ketone - Amine - Ether - Amide - Ester - functional groups - Alkyl - An alkane missing a hydrogen Aromatic compound - Cyclic, planar, with every atom of the aromatic ring having a p orbital, while obeying hackles rule of 4n+2 pi electrons Vinyl - Hydrolysis Reaction - Carboxylic Acid - pKa ~ 5 Enantiomers - stereoisomers that are non super imposable mirror images Diastereomers - - Same molecular formula, same bond connections, NOT mirrors...

EAS: friedel-crafts alkylation correct answers -the friedel-crafts alkylation makes it possible for us to install an alkyl group onto an aromatic ting -this is accomplished by reacting an alkyl halide with a lewis acid to generate a species that is electrophilic enough to react with benzene -good at forming carbon-carbon bonds EAS: Friedel-Crafts alkylation-reagents correct answers -alkyl halides are generally electrophilic but no electrophilic enough to attract the benzene ring -it was fo...
