If you are drawing the staggered conformation, all the side groups will be evenly spaced from each other if the eclipsed confrontation is being drawn, the side groups of the front will be 60 degrees from each other, with the side groups of the back directly behind. Draw the Lewis structure of the molecule below, showing all atoms and all valence electrons (bonds and lone pairs. Give the condensed formula for the compound represented by this line-angle structure: 4. Draw a line-angle structure for the compound CH 3 CH 2 CH (CH 3 )CH 2 CH 2 CH 3. You have to think about which conformation you will be drawing if it is not given. Write the condensed formula for each Lewis structure.
On the other hand, if the side group on a line is going upward, the line on the Newman projection should be directly up this should create an upside-down Y shape with the other side groups. Since the lines should be 60 degrees apart, this should look like a Y shape. Draw the skeletal formula of a branched chain aldehyde with molecular formula. If the side group written on a line is going downward, then draw that line going down from the carbon dot, along with the lines going left or right. a scientific calculator, which you are expected to use where appropriate. A side group represented by a simple line, meaning the molecule is in the plane of the page, is going to be written straight up or down. Skeletal Formulae of organic molecules are a useful concise way to describe the molecular structure of orhanic molecules. Reversely, a side group on a dash means it is going into the paper (away from you), so that can be written as a line toward the left. If a side group is on a wedge, that means it is coming out of the paper (towards you), so that can be written as a line toward the right. Draw side groups of front carbonĪnalyzing the alkane given, you can draw the Newman projection of the front carbon first. Draw the skeletal structureĮach Newman projection starts with a circle and a dot in the middle representing the two carbons, so draw that as a base. This will usually be indicated by an arrow showing the front carbon, or the dot of your Newman projection. Link Embed Export Structural formula image 3D model image MOL file Chemical. When looking at the alkane, you want to decide which bond you will be looking at and from which side. Layout Theme Desktop Touch Information Help About. Find the side view you are going to be using 8 Two chemical tests are carried out on an aqueous solution of an aromatic.
