The main type of drawing used for conformation is the\u00a0&lt;b&gt;Newman\u00a0&lt;\/b&gt;drawing. The rotations around the covalent bonds are referred to as the single bonds that are the only parts that are active with rotations. If we consider these bonds as axis points or lines, we can understand that only in these areas can rotations take place.&lt;br \/&gt;&lt;img class=&quot;aligncenter size-full wp-image-5267&quot; src=&quot;https:\/\/chemistryscore.com\/wp-content\/uploads\/2019\/11\/Screen-Shot-2017-11-18-at-11.52.26-AM-768x510.png&quot; sizes=&quot;(max-width: 768px) 100vw, 768px&quot; srcset=&quot;https:\/\/chemistryscore.com\/wp-content\/uploads\/2019\/11\/Screen-Shot-2017-11-18-at-11.52.26-AM-768x510.png 768w, https:\/\/chemistryscore.com\/wp-content\/uploads\/2019\/11\/Screen-Shot-2017-11-18-at-11.52.26-AM-768x510-300x199.png 300w&quot; alt=&quot;&quot; width=&quot;768&quot; height=&quot;510&quot; \/&gt;\">conformation<\/a>.<\/p>\n<p>The 2 main structures under the Newman projection is the staggered structure and the ellipsed structure.<\/p>\n<ul>\n<li>In the\u00a0<b>staggered structure<\/b>, the atoms are more evenly spaced out.
