What is the geometry at the central nitrogen atom in the following anion? [Hint: Draw a Lewis structure that includes all lone pair of electrons.] H₂NO Linear

For each of the following molecules, complete the Lewis structure and use the VSEPR model to determine the bond angles around each central atom. Note that the drawings are only skeleton structures and may depict the angles incorrectly.

Answer the questions in the table below about the shape of the phosphorus pentabromide (PBr,) molecule. How many electron groups are around the central phosphorus atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond. What phrase best describes the arrangement of these electron groups around the central phosphorus atom? (You may need to use the scrollbar to see all the choices.)

A classmate of yours is convinced that he knows everythingabout electronegativity. (a) In the case of atoms X and Y havingdifferent electronegativities, he says, the diatomic moleculeX¬Y must be polar. Is your classmate correct? (b) Yourclassmate says that the farther the two atoms are apart in abond, the larger the dipole moment will be. Is your classmatecorrect?

Part A) Draw the following lewis structures and give the formal charges for the atoms as well as the number of valence electrons I2 Part B)According to VSEPR theory, why are bonds and lone pairs spaced as far apart as possible? Part C)Why can we ignore the disposition of the lone pairs on terminal atoms? Part D)What are the bond angles for a molecule having an octahedral electronic geometry with two lone pairs and four bonds on the central atom?

What is the molecular shape of CF3-?

Molecular Shape:trigonal planar Questions: (Complete sentences are not necessary) 1 Examine the Lewis structure for each of the molecular shapes formed above. (ignore BrF!) Complete the following table based upon both the number of unshared electron pairs around the central atom and also the number of bond groups that are around the central atom. For example. in the following Lewis structure of PBr,, phosphonus (the central atom) has one pair of unshared electrons and three bond ypoups surrounding it. :Br: Br (Note: single, double, and triple bonds all count as single bond groups) Number of Bond Groups Number of Unshared Electron Pairs Around the Central Atom Molecular Shape Around Central Atom Linear Bent Trigonal Planar Trigonal Pyramidal Tetrahedral 2. What is the electrostatic charge of all electron groups. either shared (Le. bonds) or unshared? Since all electron groups have this same charge. do they attract or repel each other?
