Chem&219 Unit 1 Already Passed

catenation {Ans: the bonding of an element to another atom of the same element (carbon likes to do catenation)}hybrid form (resonance hybrid) {Ans: An average or blend of all of the individual resonance structures that can be drawn for that molecule. The depiction of a hybrid structure uses dotted lines to indicate partial double bond character spread equally between the possible atoms. In addition, the overall charge on the ion of can be shown by being equally divided among the possibly charged atoms in the structure (showing a partial charge on each atom like -2/3)}curved arrow notation ("pushing electrons") {Ans: A convention that shows how electron position differs between two resonance forms. - The curved arrows are used to show how the electrons in one resonance structure are redistributed to become another and so on. - The double-headed straight arrow in between each pair of structures indicates that they are resonance structures of each other and contributors to the hybrid structure. Resonance typically involves moving lone pairs and/or the pairs involved in a double or triple bond. Single bonds are not involved in resonance, as moving a single bond pair would result in a change of connectivity
