Introduction To General, Organic, And Biochemistry
- Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died. Q.) Write a Lewis structure for methyl isocyanate and predict its bond angles. What is the hybridization of its carbonyl carbon? Of its nitrogen atom?arrow_forwardA. Structural Isomerism of Alkanes Construct models for the five alkanes that have the molecular formula C6H14. All five of your models should have the same number of each type of atom, but they should have the atoms connected in a different order. Thus the molecules they represent are structural isomers of one another. Note the tetrahedral geometry of each carbon atom. Draw an extended and a condensed structure (NOT skeletal/line angle) of each structural isomer, then determine its IUPAC name. Recall that since the IUPAC name specifies the number of each type of atom and how they are connected, each structural isomer will have a different name. Each name should very specifically describe the structure.

Show the proper VSEPR shapes of all molecules (meaning VSEPR shapes with proper bond angles) and used dotted or dashed lines to indicate the hydrogen bonds. Indicate 4 different H-bonds: 1) ethanol and nitrogen trihydride 2) ethanol and dihydrogen monoxide 3) dihydrogen monoxide and nitrogen trihydride and then 4) between the two ethanol molecules.arrow_forward
- To expand on the discussion of carbon valence and hybridization, provide two simple hydrocarbons that have carbon atoms ranging from 3 to 8. Identify the hybridization and bond angles with respect to the carbon atoms. Number the sigma bonds and pi bonds present. Include a drawing of their structure.arrow_forwardwhat is the term used to describe organic reactions in which each atom of a diatomic molecule is transferred to one of the carbons in a double bond?arrow_forwardConsider the compound C₂H₃N. Which one of the structures in Figure 4 is the best representation of this compound based on your current knowledge? * 1 - A 2- B 3 - C 4- D 5 - All these structures are good representations of the compound.arrow_forward
- One family of disinfection byproducts that result from the reaction of chloramines with natural organic matter in water are called the halomethanes. These are molecules where the hydrogen atoms in methane (CH4) have been replaced with atoms from group 7 of the periodic table (i.e. halogens). Draw and submit pictures of the Lewis structures for each of the following halomethanes: CH3Cl CCI CBrCizarrow_forwardIn terms of organic chemistry how do you know if an atom has ionic bonds or covalent bonds and how do you know if it has just one of these or if it has both? Could you provide some examples of what an ionic bond looks like, covalent bond looks like, and what an atom would look like with both of these?arrow_forwardDraw the geometric structures of all the molecules. Write all bond angles and write the kind of geometry observed (linear/trigonal planar/tetrahedral) CH₃CH₃ = CH₃COH = CH₃OH = CH₂CH₂ =arrow_forward
- These two different C2H6O compounds are called structural (or constitutional) isomers - compounds with the same molecular formula but with different connections among their constituent atoms. If you must break and make new bonds in order to convert one structure into the other (not simply rotate the model around), then they are structural isomers. The concept of isomers is very important in organic chemistry and biochemistry. This is also another instance where condensed formulas can be very useful because they can help you distinguish two isomers apart even when you don't have models. Exercise 8) Can your models be interconverted by rotating bonds, or must the bonds be broken first? What does that mean about these two structures?arrow_forwardDraw the Lewis structure of acetic acid, CH3CO2H, clearly indicating all non-bonding pairs of electrons. Even though nitrogen and phosphorus have the same number of valence electrons, nitrogen can only bond to chlorine four times forming NCl4+ but phosphorus can bond with chlorine five times forming PCl5. Explain. Draw all the isomers of C4H9Br, using bond-line formulas. Draw the Lewis structure of the nitrite ion, NO2–, clearly indicating resonance contributors as well as non-bonding pairs of electrons and formal charges, as relevant. Nitromethane is a polar molecule but contains 2 equal polar covalent bonds. Briefly explain why and draw a relevant 3-dimensional structure to show the overall dipole moment of the molecule. Draw all isomers of C6H12O that are aldehydes.arrow_forwardMethylcyanoacrylate is the active ingredient in super glues. Its Lewis structure is (a) Give values for the three bond angles indicated. (b) Indicate the most polar bond in the molecule. (c) Circle the shortest carbon-oxygen bond. (d) Circle the shortest carbon-carbon bond.arrow_forward
