Draw a Lewis structure for methyl isocyanate, CH3NCO, showing all valence electrons. Predict all bond angles in this molecule and the hybridization of each C, N, and O.

What are the angles a and b in the actual molecule of which this is a Lewis structure? Н Н Н Н olb Н Note for advanced students: give the ideal angles, and don't worry about small differences from the ideal that might be caused by the fact that different electron groups may have slightly different sizes. 18 Ar b = ||

A, B, and C

Please explain

Picric acid, a benzene derivative shown below, was once used in landmines because it is sensitive to shock. What is the electron domain geometry, hybridization and bond angles of the carbon atoms? NO2 C NO2 NO2

all of the orbital overlaps in NCO ‒---- Which of the following statements is TRUE? Select one: Pi bonds are stronger than sigma bonds. The sp2 hybridization scheme for carbon allows for the formation of two pi bonds. A carbon-carbon triple bond consists of one π bond. Pi  bonds can hold 4 electrons: 2 above the bond axis, and 2 below the bond axis. A molecule with the VSEPR class AX4E2 will have a central atom that is sp3d2 hybridized.

2) a) Consider the following molecule . Given what you have learned about hybridization theory, draw an image or images explaining the bonding situation in this molecule. I want you to draw out all of the orbitals, hybrid orbitals and how they overlap to form the bonds in the molecule. Indicate the % s or p character in the given atomic and hybrid orbitals. Which C-C bond or bonds are the longest? In a paragraph or so explain the image or images you just drew. b) Lastly, consider the molecule below. Indicate the Molecular formula, the molar mass, label the hybridization of each atom except for hydrogen, indicate any chiral centers with a *, which bond or bonds are the shortest, identify by name of each functional group with an arrow pointing to the group.

Consider an iodine tetrafluoride cation (IF4+) How many valence electrons does this molecule contain? How many lone electron pairs surround the central atom? How many regions of electron density surround the central atom? What is the electron geometry of this molecule? What is the molecular shape of this molecule? Is this a polar molecule? What is the hybridization of the central atom?
