Curved arrows chemistry
WebJan 22, 2024 · Curved arrow notation is used in showing the placement of electrons between atoms. The tail of the arrow begins at the electron source and the head points to where the electron will be. Make sure the arrows are clear including the single and half headed arrow. The reader must know the flow of the electrons. Common Examples http://www.chem.ucla.edu/~harding/IGOC/C/curved_arrow.html

WebThe HCl + OH – reaction, for example, is depicted by drawing two curved arrows. The first arrow originates at one of the lone pairs on the hydroxide oxygen and points to the ‘H’ symbol in the hydrogen bromide molecule, illustrating the ‘attack’ of the oxygen lone pair and subsequent formation of the new hydrogen-oxygen bond.
WebNov 10, 2024 · What are curly arrows? They’re a shortcut to rationalize what’s happening during a reaction. Mainly used in organic chemistry, they illustrate which bonds are broken and formed or how charges are … WebNov 22, 2024 · The purpose of the curved arrow is to show movement of electrons from one site to another. Electrons move from the tail to the head. Most of the arrows you’ll see have a double-barb at the head, representing the movement of a pair of electrons. (note: there are also single-barbed arrows depicting the motion of a single electron; 2.
