Replace one of the H atoms in the ethane model with a Br atom, to form ethyl bromide CH3CH2Br, and draw a projection (lewis) and a perspective drawing. Does replacing different hydrogen atoms in CH3CH3 to produce Ch3CH2br give you different isomers? (i.e. Are all the hydrogen atoms equivalent?) How many isomers of CH3CH2Br can you construct? Make a model of one other conformer of CH3CH2Br. DId you need to break any bonds to form the second conformer from the first?

Perspective drawings of Chair and Boat Conformers fo Cyclohexane (C6H12). Note it is impossible to place all the carbons in the same plane without straining the bonds. Take two opposite carbons and pull both of them up to make one conformation adn then pull one of them down to make the other conformation. Can you inercovert one conformer int othe other without breaking any bonds? Explain why these represent conformers and not isomers.
Look at a cyclohexane model:a. Mark the axial bonds. Hold carbon atoms 1, 2, 3, 4, 5, and 6 firmly and flip up carbon 4. What is the resulting conformation? b. Then holding carbons 2, 3, 4, 5, and 6 firmly, flip down carbon What is now the resulting conformation?

Molecules that have the same molecular formula, but different atomic connections are called constitutional isomers. Draw and name the five constitutional isomers of C6H14. Is this correct answer from this paper that I draw for the name the five constitutional isomers of C6H14? Can you explain to me that why is the different atomic connections are called constitutional isomers?

For each attached compound drawn below:a.) Draw representations for the cis and trans isomers using a hexagon for the six-membered ring, and wedges and dashed wedges for substituents.b.) Draw the two possible chair conformations for the cis isomer. Which conformation, if either, is more stable?c.) Draw the two possible chair conformations for the trans isomer.

In the next chapter we'll look at cycloalkanesâ€”saturated cyclic hydrocarbonsâ€”and weâ€™ll see that the molecules generally adopt puckered, nonplanar conformations. Cyclohexane, for instance, has a puckered shape like a lounge chair rather than a flat shape. Why?
Using your model of butane (CH3CH2CH2CH3) , complete the following graph of the anglebetween the two Me groups vs. potential energy. a. Label each Newman projection of butane on the graph with the words staggered, eclipsed, gauche, and anti, as appropriate. (Note that some structures will have more than one label.) b. Draw a wedge and dash bond representation of butane in its lowest P.E. conformation.
This is done by removing an unshared pair from each of two adjacent atoms and adding one electron pair as a second bond between the atoms. Each such operation reduces the number of electrons in the trial structure by two. Removing the unshared pairs of electrons on the carbon atoms and adding a second carbon–carbon bond gives a structure in which there are four electrons involved in a double bond between the carbon atoms. The trial structure now contains electrons ____ and is correct.
