I don't have a molecular model kit but if you were to have one, how would you draw and answer the bolded parts of the following instructions:
1. build 1-butene using the molecular models, draw it, and explain why does not make any sense to specify cis- and trans-1-butene while you must specify cis- and trans-2-butene in order to draw the correct molecule
2.Using the Cahn-Ingold-Prelog rules, build with molecular models (E)-2-bromo-2-pentene and (Z)-2-bromo-2pentene, then draw as line structures and label these

For this problem, I strongly encourage you to build molecular models! Hint: provide base names for both structures. They both have the parent name of 2-bromo-3,4-dimethylpentane (don't forget your long- chain of carbons). The following structures are: "111110 not isomers constitutional isomers O enantiomers diastereomers identical

Hi,
These two questions have come up in my organic chemistry course
but I'm not sure how to do them.
I also have an extra question based from the first cycloalkene
question; when is it/is it not applicable to define cis/trans
isomers? And how do you define them based on the wedges and
dashes?
Any help will be greatly appreciated,
Thank you

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
