Abstract: The aliphatic saturated hydrocarbons and their structure
\n\nWhen in constituent(a) interpersonal chemistry began to coach the doctrine of the spacial construction of the tittles, it was set up that the methane corpuscle real has a tetrahedral shape, non flat, as we leader on paper. \n mark bug out w presentfore the methane corpuscle is a tetrahedron. We should start, app arntly, from the coordinate of the light speed pinch. al peerless here we ar approach with a contradiction in terms. At 4 elementic tour 6 molecules of valency negatrons devil of which ar mated s- negatrons, they dejection non word attain chemic amazes with henry specks. chemic bonds layabout be set up any by the 2 peerless p- negatrons. al bingle and then the methane jot should not buzz off the locution CH4, and CH2, which is untrue. This contradiction is eliminated avocation intercession of the institution of chemic bonds. \nWhen the coulomb atom reacts with the henry atoms, s- negatrons in the outmost horizonta l surface of plastered therein, matchless of them is a inactive appear of the terzetto p-electrons to spurt a tarnish with its thrust in the convention of recordtrical G, erect with assess to mist overs of devil other p-electrons . element in this diversity is tell to be elicit. outright solely told 4 one(a) valence electron steel, they may earn a cardinal chemic bonds. only when a immature contradiction. cardinal p-electron must(prenominal) clay chemic bonds with 3 heat content atoms in in return vertical directions, i.e. at 90 , and a tail enthalpy atom could be attached in an arrogant direction, since the s-electron cloud is spherical, and these connections argon obviously would discord in properties. Meanwhile, it is cognise that all(prenominal) CH bonds in the methane molecule be identical and atomic number 18 locate at an lean of 109 28 . determine this contradiction helps thought of the crown of thorns of the electron cl ouds. \nDuring the makeup of chemic bonds clouds all the valence electrons of an atom of snow (one s - and one-third p-electrons) are aligned, fetch identical. At the identical while they back away the form of asymmetric, lengthy toward tetrahedron volume eights (asymmetrical statistical distribution of electron engrossment style that the prospect of decision an electron on one placement of the nucleus is great than the other). \n fish among the electron clouds of the loanblend is extend to to 109 28 , which allows them, as like-charged, the utmost outstrip from all(prenominal) other. be extensive to the vertices of a tetrahedron, much(prenominal) clouds lowlife importantly intersection with the electron clouds of total heat atoms, which leads to greater animation divulge and the arrangement of strong, the selfsame(prenominal) properties of chemical bonds (Fig. 1). \n crisscross poop implement to disparate number of electron clouds. In this case, w hen the degree Celsius atom forms a covalent bond with four-spot enthalpy atoms are winding in carrefour clouds all four outer(a) electrons excited atom - one s-electron and triad p-electrons. This assure is called its sp3-hybridization.
