nomenclature of alkanes, alkenes and alkynes exercises

Only one carbon in a hydrocarbon is allowed to rotate. The fundamental difference between alkanes and alkenes are the presence of double bonds and triple bonds between carbon-carbon atoms, respectively. The fact that the given structure or formula is an alkane can easily be determined from the general structure C. and the suffix -ane in the name of the compound. Exercise 11-24* Show the structures of the products expected in each step of the following sequences. The fact that the given structure or formula is an alkane can easily be determined from the general structure CnH2n+2 and the suffix -ane in the name of the compound. Why is it difficult to hydrogenate a tetrasubstituted alkene such as 2,3-dimethyl-2-butene? Exercise 11-21 It is possible to synthesize two isomeric cycloalkenes of formula $$\ce{C_8H_{14}}$$. Show how this substance can be formed. Each of the substituent groups thus identified must be assigned the proper name. Write the bond-line structure for each compound as if it were correct and then give the correct IUPAC name. Examples of alkenes include: Ethene (C2H4), Propene (C3H6). The proliferation of organic chemistry gave rise to a number of organic compounds with broadly the same structural formula. b. Although they do not contain any functional groups, they form the basic framework upon which subsequent organic structure is built upon and are thereby also important when it comes to nomenclature rules. Suggest possible structures for $$A$$ and $$B$$.

(11) Translate these skeletal structures into condensed formulas and provide the IUPAC name of each. Let us look at the IUPAC names of alkane, alkene and alkyne along with the rules for naming such compounds. The simplest are the alkenes, which are hydrocarbons which have carbon-carbon double bond functional groups and are unsaturated hydrocarbons with the molecular formula is $$\ce{CnH2n}$$, which is also the same molecular formula as cycloalkanes . By now, we know that alkenes are important components of rubber and plastic products but what are alkenes. c. Ethene is more easily hydrogenated catalytically than methanal $$\left( \ce{CH_2O} \right)$$. a. Exercise 11-15 Alkynes react more slowly than alkenes with permanganate and usually give dicarbonyl compounds. b. cis-cyclohexane-1,2-diol Exercise 11-19 A serious contamination in butenyne made by dimerization of ethyne with cuprous ion is 1,5-hexadien-3-yne. Alkanes are the most basic type of hydrocarbons which have no double or triple bond functional groups in the structures. If the double bond is at the middle of the compound, the nearest substituent rule must be employed. What product would you expect from the hydroboration of 2,4-dimethyl-1,4-pentadiene with $$\ce{BH_3}$$? Explain how you could use simple chemical tests (preferably test-tube reactions) to identify the contents of each bottle. To work this problem you will need to determine whether, when one starts with optically active 3-methylhexane, the various possible intermediate structures in Figure 11-2 would be chiral or not and how many steps back one would have to go to get to an achiral system.
