FacebookTweetPin Bond-line structures, also called line-angle or skeletal structures are simple representations of organic molecules that will be used throughout your organic chemistry class. Understanding and being able to draw these structures is crucial. How To Read A Bond-Line Structure In a bond-line structure, carbons are not shown. Instead, ends of the lines and lines…
FacebookTweetPin How To Determine If The Molecule Is Chiral? A chiral molecule is a molecule whose mirror image is non-superimposable. An example that is usually given in textbooks is that of our hands. Our hands are mirror images of one another. Yet, if you try to superimpose them on top of one another, it will…
FacebookTweetPin Write a balanced equation for the reaction of gaseous carbon monoxide with hydrogen gas to form gaseous methane (CH4) and liquid water. Solution: If the question says solid, we need to write (s) next to the compound, liquid means (l), gaseous means (g) and aqueous means (aq). Gaseous carbon monoxide is CO(g). Gaseous hydrogen…
