Please answer number 3 * Pill in the following blanks A cycloalkadiene with 8 cartons will have the molecular formulaCH An alkene cowtains wo dirferent bonds between Csp carbons called abondand abond. The double bonds in vegetable oils and natural rubber all have theconfiguration. Oily liquid fatty acid esters in peanut butter can be turned into solids by catalyticover a metallic Pd (or Ni) catalyst. The anti-addition of bromine to cyclohexenegives-1,2-dibromocyclohexane. A 2° alkyl bromide is produced whenisadded to a trans-disubstituted alkene.2. Answer the following questions using only the terms Less or More.heat is evolvedduring catalytic hydrogenation of disubstituted alkene than with a trisubstituted alkene. In additionreactions of H-X to an alkene, the proton is attached to the-substituted carbon. Theaddition of borane (BH3) to a 1-alkene gives an alkylborane with the boron bonded to thesubstituted carbon. A 3° carbocation isstable than a 2° carbocation.3.

Ethers (general formula R—O—R)have many important uses. Until recently,methyl tert-butyl ether (MTBE, right)was used as an octane booster and fueladditive for gasoline. It increases the oxy-gen content of the fuel, which reducesCO emissions. MTBE is synthesized bythe catalyzed reaction of 2-methylpropene with methanol.(a) Write a balanced equation for the synthesis of MTBE. (Hint:Alcohols add to alkenes similarly to the way water does.)(b) If the government required that auto fuel mixtures contain2.7% oxygen by mass to reduce CO emissions, how many gramsof MTBE would have to be added to each 100. g of gasoline?(c) How many liters of MTBE would be in each liter of fuel mix-ture?

In the next chapter we'll look at cycloalkanesâ€”saturated cyclic hydrocarbonsâ€”and weâ€™ll see that the molecules generally adopt puckered, nonplanar conformations. Cyclohexane, for instance, has a puckered shape like a lounge chair rather than a flat shape. Why?
If one hydrogen in a hydrocarbon is replaced by a halogen atom, the number of isomers that exist for the substituted compound depends on the number of types of hydrogen in the original hydrocarbon. Thus there is only one form of chloroethane (all hydrogens in ethane are equivalent), but there are two isomers of propane that arise from the substitution of a methyl hydrogen or a methylene hydrogen. How many isomers can be obtained when one hydrogen in each of the compounds named below is replaced by a chlorine atom? a. n-pentane b. 2-methylbutane c. 2,4-dimethylpentane d. methylcyclobutane
. With very reactive agents, such as the halogen elements, alkanes undergo reactions, whereby a new atom rep laces one or more hydrogen atoms of the alkane.
