For the molecule allene, H2 C = C = CH2, give the hybridization of each carbon atom that the central carbon is sp2, terminal carbons are also sp2. A True B False Question 2 A molecule with an odd number of electrons can be diamagnetic. A) True B False

Answer the questions below about the highlighted atom in this Lewis H-0―C= | C-H H- - C=0 | H In how many sigma bonds does the highlighted atom participate? In how many pi bonds does the highlighted atom participate? What is the orbital hybridization of the highlighted atom? П □ 0

3. Give the molecular formula for each molecule below. Give the hybridization and the electronic and molecular geometry for the highlighted atoms in the following structures. OH gl a) b) N C)

A model for BrF3 is shown in the Jmol window. BrF3 has T-shaped geometry. ball & stick ✓ + labels Rotate the molecule until you have a feeling for its three-dimensional shape. How many F atoms are bonded to the central Br atom? Are all of the positions about the central atom equivalent, or are there two kinds of positions? A T-shaped molecule can be derived from a trigonal bipyramidal molecule by removing two of the outer atoms. Would the atoms removed be both axial, both equatorial, or one of each? What approximate angle at the Br atom does the unique F atom make with either of the other two F atoms? For practice, type in the name of the geometry of the molecule: degrees. Previous
