Agenda Discuss bond angles Review hybridization Work on determining orbitals involved in

bonding Write Results for qualitative analysis lab

Day 3

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

Orbital Shapes

Explains the covalent bond by quantum mechanics◦ Orbitals overlap – gives strength to bond◦ No more than 2 electrons in both orbits

Hybridization◦ Energy level between s and p

Valence Bond Theory

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
