- What are the hybridizations of the two alkyne C atoms before and after the click reaction?Members of this series are not as chemcially reactive as the other hydrocarbons, and each has a higher molecular weight as a result of an additional -CH_2_. (That's suppose to be a small two) A) hydrocarbon B) polymer C) alcohol D) paraffin Can you help me understand which one it is please?!In the next chapter we'll look at cycloalkanes—saturated cyclic hydrocarbons—and we’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?
- 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.How many ifs are lost from the molecular formula of pentane if the ends are joined into a ring(changing the parent name of the molecule to cyclopentane)?Consider the molecule 1-bromo-2-methylbutane. C3 and C4 should be drawn as Et as in theexample. This group is called an ethyl group and can be considered a sphere about twice the sizeof a methyl group. Draw the following Newman projections sighting down the C1C2 bond... a. The lowest potential energy conformation. b. The highest potential energy staggered conformation.
- 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.Which line (A or B) corresponds to the energy change for an ortho/para substitution?Draw the most stable conformer of the following compounds, using Newman projections.
- Why is the C-C bond length of an alkyne shorter than the C-C bond length of an alkene? O The orbitals are physically smaller due to mores character. O Pi bonds are weaker so more pi bonds creates a shorter bond. O There's a triple bond instead of a double bond.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?assume that substitution occurs and only once
