Depending on how long the chain is, you would name the compound based on the chain. The ring would then be considered a substituent. But if the ring has more carbons than the chain, then the chain would be considered a substituent.

So the answer is actually the last option (you misread, the last option in the course reader actually reads "Br2 acts as an electrophile.") The reason being is that the ethene molecule is electron rich with its double bond so in the halogenation reaction, the electrons from the double bond...

No, you indicate which carbon should be your primary carbon based on the order in which you can achieve the lowest number associated with each substituent. If you look at the example, you can see that the correct numbering is the one in which the substituents have the lowest carbon number, not which...

In class, we went over electrophilic addition reactions and nucleophilic substitution reactions. There are plenty of different types of reaction mechanisms, but these are the ones we went over and I'm pretty sure we just have to worry about these for the quiz. The reaction in question 5 is an electr...

Basically, when the slow step involves an intermediate you use the fast step to solve for the concentration of that intermediate and use that substitution to write the rate law of the overall reaction. You can look at the example in the course reader for reference, but try looking at is as a substit...

No, it just means that an increase in temperature won't raise k as much because not as much heat is required to overcome the lower Ea.

If you look at the standard reduction potentials (pg A17 in Appendix 2 in the book) the reduction half-reactions are listed in order of strongly oxidizing to strongly reducing. The stronger the reduction rxn (more positive voltage) and the less favorable the oxidation rxn (less positive voltage) the...

2H20 + 2e- --> H2 + 2OH- has a negative reduction potential because this chemical equation shows a reduction reaction (H+ from the H2O molecule is being reduced to H2 with and oxidation number of 0) As a result, this reaction would not be a suitable candidate for the anode because it is not a strong...

Half rxns: 12e- + 12H2O + P4 --> 4PH3 + 12OH- Reduction (multiplied by 4) 8OH- + P4 --> 4H2PO2- +4e- Oxidation (multiplied by 12) _______________________________________ 48H2O + 16P4 + 96OH- --> 16PH3 + 48H2PO2 + 48OH- Divide the equation by 16 3H2O + P4 + 3OH- --> PH3 + 3H2PO2-

In a galvanic cell the spontaneous redox rxn creates the flow of electricity (which is produced by the flow of electrons from the anode- which is negative due to electron build up- to the cathode- which is positive since it is gaining electrons) The salt bridge is what joins the halves of the electr...
