Day 3

1. Day 3 Agenda • Discuss bond angles • Review hybridization • Work on determining orbitals involved in bonding • Write Results for qualitative analysis lab

2. Effect Bond Angles p399 • Lone pairs • Require more space • Reduce bond angle • Double/triple bonds • Require more space, therefore reduce bond angle • Highly electronegative elements • Draw e- towards self, increasing bond angle

18. Orbitals

20. Qualitative Analysis Lab Report • You’re on your own this time! • Intro – quality – (qualitative) • FLOW • M & M – in your own words • Past tense of what you did with mishaps • Results – may be the same between partners • Preferable • Conclusions – on your own
