Chemistry Project Exam

BTiGC (CHM1045) Due date: December 8 (midnight) Individual accepted.

Bonding Theories in General Chemistry Applying Lewis Model, VSEPR, Valence Bond and Molecular Orbital Theories.

The Concept Map (up to 40 points) • Prepare a concept map on “molecular shapes”. The concept maps must include the

following “categories” (information): Octet rule, Lewis and VSEPR theory, Valence Bond (and hybridization), and Molecular Orbitals.

Construct a 3D model (up to 25 points) Choose a molecule with everyday life application, like a drug, natural biological, organic synthetic, other. The Molecule must contain the following

• 10 atoms

• At least 1 double and/or triple bond (sigma and pi bonds).

• Prepare a 3D model (virtual or real). Virtual: you can use an app (3D Molecules Editor), or on your computer (https://molview.org), or any other you find.

“Show and Tell” (up to 40 points) The video and voice recording are mandatory. Failure to submit the video and over-the voice recording will automatically result in zero (0) points for this item.

Prepare a voice video (10-15 minutes) including the following:

• Explaining your concept map.

• Tell 3 facts about the molecule you choose

• Use your concept map to explain your model. In your explanation include the following information: pi and sigma bonds, hybridization and, if present, resonance and “charge distribution” (electron rich/electron poor areas).
