Correct Answer-A nucleus Which of the following can be found in both eukaryotes a...

-al -ol or hydroxy- -one -oic acid -oate -ether or alkoxy- Iodo- or Bromo- etc. -amide Amino- or -amine - Aldehyde Alcohol Ketone Carboxylic acid Ester Ether Alkyl halides Amide Amine Constitutional Isomer - A compound with the same atoms but different atoms bonded to each other Stereoisomers - Molecules with the same atoms differing only in 3D configuration Enantiomers - Stereoisomers with exactly opposite stereochemical designations at all stereogenic carbons Dia...

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...

CHEM 2302 Exam 2 Questions & Answers 2023/2024 nucleophilic aromatic substitution by addition-elimination - ANSWER-aryl halides with electron-withdrawing groups (NO₂) in ortho or para position can react with nucleophiles to substitute a leaving group for nucleophile resonance stabilized anion intermediate rate increases with more electron-withdrawing roups or more electronegative halogen nucleophilic aromatic substitution by elimination-addition - ANSWER-aryl halides without an electro...

alkyl halide - Answer-compounds in which a halogen is connected to an sp3 hybridized carbon atom 2 types of rxn's alkyl halides go under - Answer-substitution and elimination substitution reaction - Answer-when treated with a nucleophile, the nucleophile replaces the halogen elimination reaction - Answer-when treated with a base, a pi bond will form creating an alkene what functions does the halogen serve in an alkyl halide - Answer-1) halogen withdraws electron density leaving the ...

1 CHM 219 MODULE 4 EXAM | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ Organohalides Correct Answer: Organic molecules contains Halogen atoms. Ex. Algae, Mollusk, sponges, can be industrially used - solvents, insecticides, herbicides, cleaning fluids, fire retardants, refrigerants. Can also be used as inhaled anesthetic. More important in organic chemistry because of theur reactivity. Two of the most important reaction types typical of organic Halides are.... Corr...

What is the mechanism of the reaction between silver nitrate and tertiary alkyl halides? Which Lab? correct answer: SN1 and Lab 9: Preparation of 2-Chloro-2-Methylbutane *Starting Material : Tertiary Alcohol * Nu- : weak base but strong Nu- (Cl) *SN1 *Water is LG In lab 9 what is the purpose of HCl? Limiting Reactant? correct answer: -To convert the alochol (OH) from a poor LG (OH) to a great LG (OH2+) - To provide a strong Nu- (Cl-) LR= Alcohol In lab 9 why did we use sodium ...

Chem 219 Unit 4 Exam with Verified Solutions What are the four halogen elements? - Answer -F, Cl, Br, I organohalide compounds - Answer -Organic molecules containing halogen atoms (F, Cl, Br, I) Examples of how organohalide compounds are used by humans - Answer -- have been found in marine life (algae, mollusks, sponges, etc.), bc they metabolize the high concentrations of inorganic chlorides and bromides that are found in the seas. - Industrially, organohalides find uses as solvents, inse...
