Priority of Ethers

Because ethers are unique and are treated as a substituent rather than a functional group, they do not get the same priority as other functional groups like alcohols or ketones. However, would an ether get priority over a double bond or not? For example, how do you name CH 3 -O-CH 2 -CH 2 -CH=CH 2 ....

Stereospecific Reactions

What is a stereospecific reactions? From my understanding, is that it is a reaction that is specific to the shape of the reactants and depending on whether the same molecule is cis or trans, the reaction will change.

Alkyl Groups

When indicating what alkyl group is attached to an amine, how do you indicate if there is more than one amine in the chain? For example "N-ethyl-N-methyl-1-propanamine", how would you differentiate between the two amine groups?

Electrophilic Aromatic Substitution

For electrophilic aromatic substitution, does an electrophile and a base always have to be present? Also how does the concentration of the base affect the overall reaction rate?

Arrows

Will there ever be an example where we have to differentiate between single-headed and double-headed curved arrows? What is an example for a single-headed curved arrow?

Cycloalkanes - Different Types

There are types of cycloalkanes that include more than one structure of cycloalkane - bicycloalkane and spirocycloalkane. Is that something that we are required to know for the next quiz. Also, how would the bonds be drawn in the simpler structures that we use for organic molecules?

Quiz 3 Preparation

For the first question, the compound was named 1-chloro-3-methyl-cyclopentane. I was just wondering whether the 1 and 3 are interchangeable. If not, why is the chlorine substituent given the number placement of 1?

Enthalpy, q=mc(delt)T

During my discussion, I learned of an equation in which the specific heat capacity, instead of Cs is Cm. What is the constant Cm and how is it different from Cs? Also, how frequently would Cm be used in problems in class as it wasn't mentioned in the course reader (to my knowledge)?

Question 3.117 a

Question: Structural isomers are molecules that have the same formula but in which the atoms are connected in a different order. Two isomers of disulfur difluoride, S 2 F 2 are known. In each the 2 S atoms are bonded in each other. In one isomer each of the S atoms is bonded to an F atom. In the oth...

Re: Molecular Shape of Water

It's actually bent because despite the two bonds between the oxygen and the hydrogen atoms, the oxygen atom also has a lone pair of electrons which repels the hydrogen-oxygen bonds, forming a V-shape. This is also known as bent.
