A2 Chemistry Revision This flash card aims to help student learning A2 Chemistry 0.0 / 5 ? ChemistryTransitional Metal / OrganicA2/A-levelCIE Created by: Tony YuCreated on: 06-12-18 06:08 In benzene, why does the C=C & C-C bond has the same length? There is a resonance of electrons so all the C-C bonds in benzene are equivalent. 1 of 12 When can resonance can occur? When there is alternating adjacent C=C & C-C bond. 2 of 12 What is the name of catalyst for elecrophilic substitution for benzene? Halogen carrier. 3 of 12 What is the name of the positive ion used in the nitration of benzene? Nitronium ion. 4 of 12 What is the name for alkylation of benzene? Friedel-crafts reaction. 5 of 12 Why phenol has higher m.p. than benzene? It can from higrogen bond with each other due to the presence of O-H bond. 6 of 12 What is the name of phenol's salt? Phenoxide. 7 of 12 What is a reagent? It is something that you can take out of a bottle. 8 of 12 How to find the overall Kp of a multi-step reaction. Multiply all the Kp values of the individual reactions. 9 of 12 Define ligand. It is a molecule or negative ion which has a lone pair of electrons, which can use its lone pair to form co-orginate bond to a metal. 10 of 12 Define transitional metal. An element/atom which forms at least one stable ion containing a partially filled (1-9) d-orbital. 11 of 12 In tetrahedral complex, which orbital(s) has higher energy level? dxy & dyz & dxz 12 of 12
