For the cycloalkanes, one hydrogen atom has to be removed from each end of the hydrocarbon chain, therefore resulting to a deficit of two hydrogen atoms unlike in the case of alkanes. What is the three dimensional structure of methane? Why? Methane represents a tetrahedral structure. This is because the structure permits the orbitals to be as far apart and the hydrogen atoms directed to the corners of the tetrahedron when the carbon is bonded to four other atoms
Name one structural and one chemical difference between acetylene and ethylene. Give reasons. Acetylene has a carbon to carbon triple bond whereas ethylene has a carbon to carbon double bond. Acetylene is made by high temperatures partial oxidation of methane while ethylene is made from the hydration of ethane What is the formula of 1, 3-butadiene? CH2==CH ¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬ CH==CH2 Why is benzene much less reactive than 1, 3, 5-cyclohexatriene?
Benzene has a carbon to carbon double bound that is alternating and strongly attracted to another therefore making it unable to undergo an additional reaction like 1, 3, 5-cyclohexatriene who’s covalent bonds allows it to undergo an additional reaction. Why is the benzene molecule represented as “a flat cyclohexane with a ring inside? ” Benzene has alternating double bounds that are usually in rotation in its structure Why do cis and trans isomeric compounds exhibit different properties?
In cis isomeric compounds the methyl groups are located o the same side of the molecule while in trans isomers the methyl group are locate on the opposite sides. This in return indicates that the polarity of trans isomeric compounds is canceled out as compared to that of cis isomeric compounds. What is the difference between hydration and hydrogenation reactions? Hydration involves an addition reaction where water is used as the hydrant while hydrogenation involves a reducing reaction where hydrogen is used. Reference Robert Thornton Morrison. (1996).
