- What are aromatic hydrocarbons? Benzene exhibits resonance. Explain. What are the bond angles in benzene? Give a detailed description of the bonding in benzene. The electrons in benzene are delocalized, while the electrons in simple alkenes and alkynes are localized. Explain the difference.arrow_forwardWrite the structural formula for propylene glycol, 1,2-propanediol. Why is it classified as an alcohol? Is it a polar molecule? Should it be miscible with water?arrow_forwardWrite structural formulas for all organic compounds. State the type of reaction. Complete and balance the reaction. Name the products. Section 1. propene + hydrogen ? 2. cyclohexane + chlorine ? 3. benzene + iodine ?arrow_forward

What is the name of this compound? (Please refer to the second image attached.) A. o-cresol B. 3-ethylphenol C. 3-ethylphenol D. 2-methylphenol 3. Ingestion of this low molecular weight alcohol may cause blindness due to the production of formaldehyde A. Methanol B. Ethanol C. Diols D. Aromatic Alcoholsarrow_forwardWhich of the compounds, ethanol, C2H6O, or methanol, CH3OH, should have the higher boiling point? Why? How would the boiling point change if the atmospheric pressure increased or decreased? What is the effect of small amount of impurity on the boiling point of an organic compound? List five physical properties of organic compounds that are often measured by organic chemists.arrow_forwardThe functional group R carboxylic acid anhydrides. esters. aldehydes. ketones. amides. carboxylic acids. -0-C-R is characteristic ofarrow_forward

Draw the structures of the following: a. 3-bromo-3,4-dimethyl-1-hepten-5-yne b. Acetylene c. 1-ethynyl-2-methylcyclohexanearrow_forwardGasohol is a mixture of 90% gasoline and 10% ethanol, CH 3CH 2OH. Ethanol is considered an environmentally friendly fuel additive because it can be made from a renewable source—sugarcane. Ethanol burns in air to form CO 2 and H 2O, and, like the combustion of alkanes, this reaction also releases a great deal of energy. Write a balanced equation for the combustion of ethanol.arrow_forward
