- Indicate which of the following molecules are polar. Draw the molecular structure of each polar molecule, including the arrows that indicate the bond dipoles and the molecular dipole moment. (a) HCN (b) I2 (c) NO3) Determine whether CH3CI is polar. To do this, you must: draw the 3D structure of the molecule, use arrows to indicate polar bonds, and either use an arrow to indicate the net dipole moment or state that the molecule is non-polar.Answer the questions in the table below about the shape of the fluoroform (CHF3) molecule. How many electron groups are around the central carbon atom? Note: one "electron group" means one lone pair, one single bond, one double bond, or one triple bond.

- For the molecule pictured with the formula C3H4, the CENTER carbon atom in the molecule has lone pairs, and other atoms attached to it, electron clouds.Oxalic acid, H2C2O4, a poisonous colorless solid, is found in some vegetables such as spinach and rhubarb. It is present in concentrations well below the toxic limit, so you can't use this as a reason to refuse a helping of spinach. The order of atoms in a molecule of oxalic acid is HO2CCO2H. (a) How many unshared pairs of electrons are on each of the carbon atoms? (b) How many unshared pairs of electrons are on each of the oxygen atoms?Why is it less clear to see the electrons on HBrO2 molecular electron geometry than it is on something like H2O? I know there should be 20 electrons on HBrO2, but this leads me to an incorrect drawing. And with the correct drawing, I don't see where all the electrons are. It seems like there's only 10 total. What am I missing here?
