You will be sitting for the 9729 (new) syllabus papers. This document will instruct you on the changes you need to make to the TYS questions. The Planning question for the 9729 syllabus will be in the Paper 4 (Practical). Some concepts are no longer tested in the 9729 syllabus and the values used for some calculations are now different (e.g. molar volume at s.t.p.) which will affect your choice of the answers. You are advised to make the changes on your question papers before you attempt it . Do inform your tutors if you notice any differences which were not highlighted in this document. ---------------------------------------------------------------------------------------------------------------------------------------------- Paper 1 14 Not in syllabus 16 Amend question “What is the trend in boiling point and in electron affinity of the Group 17 elements from chlorine to iodine?” 30 Not in syllabus 31 Amend question “Carbon forms double bonds with each of the Group 16 elements…” 35 Amend question “The foll owing represents the electronic configuration of both a Group 2 cation and a Group 17 anion. 36 Amend question “1.0 mol dm –3 aqueous solutions of three elements in Group 17 of the Periodic Table…” 40 Not in syllabus Paper 2 No amendments Paper 3 1(b)(ii) Amend question “How does the extent of this reaction vary down Group 17?” 1(e) Amend question “…only two of which are cis-trans isomers of each other.” 4(e)(ii) Amend question “How would you expect the magnitudes of the lattice energies of the oxides of the Group 2 elements to vary down the group?”
