Drawing chemical structures practice
WebThe movement of mobile electrons in chemical structures and in reaction mechanisms is indicated using the curved arrow formalism. Small, curved arrows indicate the movement of electron pairs, be it from a bond or an unshared pair. For example, the movement of electrons used to arrive at structure II from I is: H C C N O H H H C C N O H H I II WebA structural formula shows how the various atoms are bonded. There are various ways of drawing this and you will need to be familiar with all of them. Displayed formulae A displayed formula shows all the bonds in the molecule as individual lines. You need to remember that each line represents a pair of shared electrons.
