True False How many structural isomers are possible for butane (molecular formula C4C10)? 2 3 4 5 Which is a difference between butyne and cyclobutyne? Cyclobutyne can't exist! Butyne's multiple bond is not as strong as that of cyclobutyne. Cyclobutyne burns much hotter than butyne because of the greater unsaturation. Both b and c are differences between the molecules. There are more inorganic compounds than organic compounds. True False The compound has the IUPAC name 4-isopropyloctane 5-isopropyloctane 5-sec-butyloctane 4-propyloctane What is the reason why there are so many organic compounds? Organic compounds are produced by living things. There are cyclic organic compounds, and none of the inorganic compounds are cyclic. Carbon atoms can form stable covalent bonds with other carbon atoms. Organic compounds can be larger than inorganic compounds Two moles of hydrogen gas would be required to convert one mole of 2-butyne into butane. True False The chemical properties of alkynes are very different from those of alkenes. True False Alkanes react readily with sodium hydroxide hydrochloric acid sulfuric acid none of the above Which of the following formulas represents an organic compound? CH4 CH4CH2CH3 CH3CH3CH3 they all do What is the characteristic of aromatic compounds that is responsible for them being named aromatic compounds? The compounds have a pleasant smell. These compounds contain a benzene ring. It must contain a hydrocarbon chain that is either saturated or unsaturated and at least 3 carbons long. There is more than one correct response. A correct IUPAC name for is 1-bromo-3-ethyl-1-methylcyclopropane 1-bromo-2-ethyl-1-methylcyclopropane 1-bromo-1-ethyl-2-methylcyclopropane 2-bromo-1-ethyl-2-methylcyclopropane Which applies to the manner in which carbon bonds in alkanes? The bonds are formed with carbon using an sp3 configuration. The bonds between carbon and other atoms are ionic. carbon to carbon bonds are expected to be double bonds. The bonds formed by carbon all use p orbitals. Alkanes are _____ in water and _____ than water. insoluble, less dense soluble, less dense insoluble, more dense soluble, more dense Which of the following formulas represents a saturated hydrocarbon? C2H6 C2H4 C3H6 C5H10 The IUPAC name for is 2-ethylbutane 2-methylbutane 3-methylpentane 3-ethylbutane What number would be used to indicate the double bond position in the IUPAC name for CH3CH2CH = CHCH3? 1 2 3 4 What is a characteristic shared by the alkanes? Solids Polar Flammable Colored Which is a difference between butene and cyclobutene? They are isomers. Cyclobutene has 2 double bonds, butene does not. The phase varience of the infrared transconductance is asymetric. Cyclobutene has fewer hydrogens than butene. The naming of organic compounds is specific. Which is an incorrect statement? The smaller of the compounds have been known long enough to have common names. The naming system of organic compounds is set out by IUPAC rules. The naming system for hydrocarbons requires the identification of the longest carbon chain. The naming system for organic compounds requires and IUPAC name and a common name. Name a difference between a saturated and an unsaturated hydrocarbon. Saturated hydrocarbons are composed of only carbon and hydrogen, and unsaturated hydrocarbons include other atoms than just carbon and hydrogen. Saturated hydrocarbons do not contain multiple bonds between carbons, but unsaturated hydrocarbons do contain multiple bonds. Unsaturated hydrocarbons a flammable, but saturated hydrocarbons aren't flammable. Saturated hydrocarbons are essentially insoluble. Unsaturated hydrocarbons are soluble. Which is a difference between butane and butene? butane burns and butene does not the presence of a double bond they are isomers the presence of a triple bond Most organic compounds contain ionic bonds. True False Which statement referring to functional groups is correct? Functional groups are where nothing happens in a chemical reaction the parts of molecules used to classify organic molecules where most chemical reaction occur both b and c Phenyl is the name given to benzene when it is a substituent of a larger molecule.
