Re: Question on organic homework #17

You number in the direction that gives all the substituents a lower number overall. If you started with 1-tert-butyl, the two methyl substituents will be numbered 3 and 4. However, if you start with the methyl labeled #1 in red, the two methyl constituents will then be 1,2-dimethyl. 1,2,4 is lower t...

Re: Cis vs. Trans

When trying to determine if a structure is cis or trans, you look at the atomic number with respect to each group bonded to each of the Carbons, so the latter! Refer to page 103 in the course reader :)

Re: Quiz 3 Winter 2017

Shouldnt number 4 be 5-butyl instead of 4-butyl? 4-butyl should be the correct answer because you’re supposed to number the carbons in the chain from the end that gives the substituents the lowest numbers. In this case, you start from the top left carbon of the cyclohexane structure and number the ...

Re: High temp, low activation energy

To answer your question, it is safe to assume that chemical reactions occur more rapidly at higher temperatures. Thus, as temperature increases, the rate at which collisions occur between molecules will also increase (molecules are moving a lot faster at higher temperatures.) This in turn results in...
