How do i do compound ii?!

Part A: Enantiomers and Diastereomers. 1. Construct a model of CH3CH(OH)CH2CH2CH3 (compound i ), as well as the model of its mirror image. Take a photo of the two models with your student card visible in the photo. The photo should clearly show that the two models are mirror images. 2. Carefully draw the line structures of all the stereoisomers of the compound using proper stereochemical notation. Any mirror images should be drawn side-by-side indicating the mirror plane. Structures should be drawn using the zig-zag style, either by hand or using ChemDraw (see note below). 3. Determine if the mirror images can be superimposed and therefore if they are enantiomers and/or diastereomers. 4. Identify the stereogenic centre(s) of the molecule (if applicable). 5. Determine the configuration at each stereogenic centre (R or S), if applicable. 6. If there are more than 2 stereoisomers, perform a full stereochemical analysis of your structures, indicating which pairs are enantiomers and/or diastereomers. 7. Repeat steps \#2 to \#6 for each of the following compounds
