For the following molecule, 2 1. what are the ideal bond angles about each numbered carbon atom? 1 degrees 2 3 degrees Show work degrees

As a general rule, MX molecules (where M represents a central atom and X represents terminal atoms; n = 2 5) are polar if there is one or more lone pairs of electrons on M. NH3 (M = N, X = H, n = 3) is an example. There are two molecular structures with lone pairs that are exceptions to this rule. What are they?

1. Which of the following species has the longest N—O bond? NO3 NO+ NO2− H2NOH

Predict the molecular structure and bond angles for each molecule or ion in Exercises 87 and 93. a. CCl4 b. NCl3 c. SeCl2 d. ICl a. NO2, NO3, N2O4 (N2O4 exists as O2NNO2.) b. OCN, SCN, N3 (Carbon is the central atom in OCN and SCN.)

Consider the following molecules: (a) CH4 (b) NH2Cl (c) BF3 (d) CS2 (i) In which compound are the bonds most polar? (ii) Which compounds are not polar? (iii) Are the H atoms in NH2Cl negative or positive?

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?

c. How many o and T bonds are there in acrylonitrile? H C=C2 a H 'N Acrylonitrile o bonds = T bonds =

Can you please do the first 3 rows of the table?

Molecular geometry—don’t know why I’m incorrect all of a sudden. Might be one shape needed that is not given in the option choices.
