Why is acetaminophen not commonly used in cats and dogs? correct answers Low therapeutic index What is the level of plasma protein binding of acetaminophen? correct answers 1. Poor protein bin...

Chapter 18 EAS Questions and Answers 100% correct Electrophilic Aromatic Substitution -reaction in which an electrophile is substituted for a hydrogen on an aromatic ring -many different types of EAS reactions based on what functional group replaces the hydrogen Alkene vs Benzene Alkenes undergo addition reactions but Benzenes react differently under similar reagents. Don't confuse the two, one is Aromatic and the other isn't. Aromatic Requirements The organic structure must...

Chem 210: Chapter 8 Correct 100% Addition - ANSWERA reaction involving an increase in the number of groups attached to the alkene and a decrease in the number Regiochemistry - ANSWERThe orientation of a chemical reaction on an unsymmetrical substrate. In additions to alkenes, the regiochemistry of the addition involves which part of the reagent adds to which end of an unsymmetrical alkene. Regioselective reaction - ANSWERA reaction in which one direction of bond making or bond breakin...

regioisomers - Answer structural isomers formed in some reaction, same formula but different connectivities nucleophile - Answer e- sources drawn to positive centers, more negative [bases are all nucleophiles] in SN2, nucleophile attacks C sp3 only if C is having e- pulled away from it (partial positive charge) electrophile - Answer C sp3 with leaving group leaving group (LG) - Answer atoms/groups that pull away e-s good leaving groups: halogens and A+ bimolecular nucleophilic...

Addition - ANSWERA reaction involving an increase in the number of groups attached to the alkene and a decrease in the number Regiochemistry - ANSWERThe orientation of a chemical reaction on an unsymmetrical substrate. In additions to alkenes, the regiochemistry of the addition involves which part of the reagent adds to which end of an unsymmetrical alkene. Regioselective reaction - ANSWERA reaction in which one direction of bond making or bond breaking occurs preferentially over all other...

What type of carbons do E2 rxns favor? - ANSWERTertiary What is a Zaitsev product? - ANSWERDouble bond formation on more substituted carbon What is a Hoffman product? - ANSWERDouble bond formation on less substituted carbon When using a stericallly hindered base (t-BuOK, LDA), which product is more favorable? - ANSWERHoffman When using Eto- or less sterically hindered ...

▪ In the periodic table, element X is in group 2 and element Y is in group 5. what is the likely formula of the ionic compound of X and Y - Ans .X3Y2 ▪ which enthalpy changes are endothermic - Ans .the bond enthalpy of a C-H bond and the second electron affinity of oxygen ▪ explain why the halogens show an increased boiling point down the group (3) - Ans .- london forces increase - number of electrons increase - more energy to break intermolecular forces ▪ predict what would h...

1. What is an alkene and its general formula? - Ans .It is an unsaturated hydrocarbon with a least one C=C bond. General formula is CnH2n 2. What is a sigma bond? σ - Ans .single covalent bond formed when two s orbitals overlap. High electron density 3. What is a pi bond? - Ans .sideways overlap of p orbitals that occur in a double or triple bond. Much weaker than sigma, low bond enthalpy and lower electrostatic attraction 4. Is an alkane or an alkene more reactive? - Ans .Alkene. cont...
