Many important compounds in the chemical industry are derivatives of ethylene (C2H4). two of them are acrylonitrile and methyl methacrylate. Acrylonitrile Methyl methacrylate Complete the Lewis structures, showing all lone pairs. Give approximate values for bond angles a through f Give the hybridization of all carbon atoms. In acrylonitrile, how many of the atoms in the molecule must lie in the same plane? How many bonds and how many bonds are there in methyl methacrylate and acrylonitrile?
Formamide, HC(O)NH2, is prepared at high pressures from carbon monoxide and ammonia, and serves as an industrial solvent (the parentheses around the O indicate that it is bonded only to the carbon atom and that the carbon atom is also bonded to the H and the N atoms). Two resonance forms (one with formal charges) can be written for formamide. Write both resonance structures, and predict the bond angles about the carbon and nitrogen atoms for each resonance form. Are they the same? Describe how the experimental determination of the HNH bond angle could be used to indicate which resonance form is more important.
Eyedrops for dry eyes usually contain a water-soluble polymer called poly(vinyl alcohol), which is based on the unstable organicmolecule vinyl alcohol:
d. Many important compounds in the chemical industry are derivatives of ethylene (C2H4). One is methyl methacrylate. What are the indicated bond angles in methyl methacrylate? Methyl methacrylate angle d = angle e = angle f=
Predict the hybridization, geometry, and bond angles for the carbon atoms in acetylene, C2H2.
Draw a line-bond structure for propene, CH3CH=CH2. Indicate the hybridization of the orbitals on each carbon, and predict the value of each bond angle.
For the following descriptions of molecules, draw the Lewis structure (showing all atoms, lone pairs, formal charges) of the molecule and show all bond angles (assuming ideal VSEPR angles). An organic compound with the molecular formula H3CNO2. C is sp2 hybridized, N is sp3 hybridized, one O is sp² hybridized, while the second O is sp3 hybridized. An organic compound with the molecular formula H2CNO*. Both C and O are sp hybridized while N is sp³ hybridized.
Use VSEPR to predict bond angles about each atom of carbon, nitrogen, and oxygen in these molecules.
2) Based on valence bond theory, which statement best describes the electron geometry and hybridization of the central atom(s) in acetylene HCCH? A) The electron geometry of the 2 carbons in acetylene is linear with a sp hybridization. B) The electron geometry of the 2 carbons in acetylene is trigonal planar with a sp2 hybridization. C) The electron geometry of the 2 carbons in acetylene is tetrahedral with a sp3 hybridization.
Eyedrops for dry eyes usually contain a water-soluble polymer called poly(vinyl alcohol), which is based on the unstable organicmolecule vinyl alcohol:Predict the approximate values for the H¬O¬C and O¬C¬C bond angles in vinyl alcohol.
Acrylic fibers are polymers made from a starting material called acrylonitrile, H2C(CH)CN. In acrylonitrile, a - CN group replaces a hydrogen atom on ethene. Draw the Lewis diagram for this molecule, give the hybridization of each carbon atom, and describe the \pi orbitals and the number of electrons that occupy each one. Draw the three-dimensional structure of the molecule, showing all angles.
