Mar 28, 2020 · CH4, commonly known as methane, is a tetrahedral structure with four hydrogen atoms forming around a central carbon atom. Pictorially, this structure resembles a pyramid in shape, with all four corners equidistant from the center.
The simplest alkane is methane: CH 4. The Lewis structure of methane can be generated by combining the four electrons in the valence shell of a neutral carbon atom with four hydrogen atoms to form a compound in which the carbon atom shares a total of eight valence electrons with the four hydrogen atoms.
However, molecular structure is actually three-dimensional, and it is important to be able to describe molecular bonds in terms of their distances, angles, and For example, the methane molecule, CH4, which is the major component of natural gas, has four bonding pairs of electrons around the central...

Nov 28, 2009 · From Al4 and C3 can say how many Al(OH)3 and CH4 formed. Al4C3 + H2O → 4Al(OH)3 + 3CH4. Now work out H from right hand side 12 + 12 H = 24H so 12H2O needed
So that's kind of combining this way of writing the molecule where you write the CH3's for the end points, but then you implicitly have the CH2 on the inside. So these are all completely valid ways of drawing the molecular structures of these carbon chains or of these organic compounds.
Burning one molecule of methane in the presence of oxygen releases one molecule of CO2[carbon dioxide) and two molecules of H2O (water): CH4 + 2O2 ---> CO2 + 2H2O The strength of the carbon hydrogen covalent bond in the methane molecule is among the strongest in all hydrocarbons, and thus its use as a chemical feedstock is limited.

CHEMICAL BONDING AND MOLECULAR STRUCTURE OCTET RULE-During a chemical reaction the atoms tend to adjust their electronic arrangement in such a way that they achieve 8 e-in their outermost electron. This is called octet rule. CHEMICAL BOND- the chemical force which keeps the atoms in any molecule together is called a chemical bond.
