Alkyl halides - Study guides, Class notes & Summaries

Alkyl halides do one of two things when they react with a nucleophile/base, such as a hydroxide ion... - correct answer (1) undergo SUBSTITUTION of the X group by the nucleophile OR (2) undergo ELIMINATION of HX to yield an alkene carbon-halogen bonds in alkyl halides are polar and the carbon atoms are electron-poor, thus, alkyl halides are ELECTROPHILES Nucleophilic Substitution Reactions - correct answer -each st...

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...

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...

SN1 Reaction - ANSWER- Unimolecular nucleophilic substitution - 2 steps - Starting with enantiomerically pure product tends to result in some degree of racemization - Retention AND inversion at stereocenter (R and S) - 1 nucleophile is replaced by another nucleophile - Carbocation INTERMEDIATE forms - Rate is dependent only on substrate concentration 1. LG leaves, forming a carbocation 2. Nucleophile attacks the carbocation, forming the product SN2 Reaction - ANSWER- Bimolecular nuc...

acetylenes = - Answer-alkynes olefins = - Answer-alkenes E = - Answer-trans Z = - Answer-cis stability of cis vs. trans - Answer-trans is more stable hydrogenation - Answer-exothermic addition of H to an alkene relate the heats of reaction for trans-butene, cis-butene, and 1-butene. - Answer-1-butene > cis-2-butene > trans-2-butene (most stable) stabilities of alkenes (substitution) - Answer-tetra- > tri- > di-> mono- > un- stabilities of alkenes (status...

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 ...

5.2: Organic Chemistry II One or more of the hydrogen atoms of a hydrocarbon can be replaced by another atom or group of atoms thus forming the other families of organic compounds. These organic families are much more reactive than the hydrocarbons, and the non-hydrocarbon portion of the molecule is called the functional group since it largely determines how the molecule behaves (functions). Replacement of one or more hydrogens of a hydrocarbon by a halogen atom (-F, -Cl, -Br or –I) resu...
