- Draw a structural formula for the alkene you would use to prepare the alcohol shown by hydroboration/oxidation. CH₂OH • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one. #[ ] در ChemDoodleⓇMake two identical models of methane with four different colored balls attached to each carbon. On one of the models switch two of the balls. Draw the two structures in stereoscopic projection (with dash, wedge, etc.). Label each hydrogen as H1, H2, etc.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?
