define tetravalency?
Because carbon posess tetravalency
Carbon can form large number of compounds. This is because of catenation and tetravalency.
Catenation and tetravalency are the properties. Because of this, carbon forms long complex structure.
Carbon is the substance which is constituent of every living and non living things. Carbon is found in many forms in nature due its special properties :- catenation and tetravalency.
catenation , tetravalency , high bond energy making the compounds stable, isomerism
A straight-chain trialdehyde is not possible due to the structural requirements of aldehydes, which contain a carbonyl group (C=O) bonded to a terminal carbon atom. In a trialdehyde, three aldehyde groups would require three terminal carbons, but this would lead to a carbon chain that cannot satisfy the tetravalency of carbon. Specifically, if one tries to extend the chain to accommodate three aldehyde groups at both ends, it would result in structural instability or violate the tetravalency of carbon. Thus, trialdehydes must have branched or cyclic structures instead.
Carbon is the smallest atom having tetravalency. Note that carbon is the atom in the uppermost* period of a wide form periodic table that includes column 14, the column in which the most common valency is tetravalency, and in general atomic size is greater the lower in a periodic table that the atom appears.___________________________*This is the second period of the table as a whole; the first period includes only columns 1 and 18.
C6H12, known as a hydrocarbon, specifically an alkane, contains single covalent bonds between its carbon and hydrogen atoms. The structure can be represented as a straight-chain or branched form, with each carbon atom typically forming four bonds to satisfy the tetravalency of carbon. In this molecule, all the bonds are sigma (σ) bonds, as they involve head-on overlapping of atomic orbitals.
The structural formula of the alkane series, which consists of saturated hydrocarbons, can be represented by the general formula (C_nH_{2n+2}), where (n) is the number of carbon atoms. In this series, carbon atoms are connected by single bonds, and each carbon atom is bonded to enough hydrogen atoms to satisfy its tetravalency. For example, the structural formula for ethane (with (n=2)) is (C_2H_6), which can be represented as (H_3C-CH_3).
The four lines surrounding the carbon molecule in the diagram represent the four covalent bonds that carbon can form with other atoms. This tetravalency allows carbon to bond with a variety of elements, such as hydrogen, oxygen, and nitrogen, enabling it to create a diverse range of organic compounds. The ability to form four bonds is fundamental to the complexity and versatility of carbon-based life.
The molecular formula C6H16 represents hexane, which consists of six carbon atoms and sixteen hydrogen atoms. In a structural drawing, hexane can be depicted as a straight chain of six carbon atoms (C) connected by single bonds, with hydrogen atoms (H) bonded to each carbon to satisfy carbon's tetravalency. The condensed structural formula can be written as CH3(CH2)4CH3, indicating the chain structure.
An atom of carbon typically makes four single bonds in a covalent molecule when there are no double or triple bonds. This tetravalency allows carbon to form stable molecules by sharing its four valence electrons with other atoms. Each bond involves the sharing of one electron from carbon and one from the other atom, resulting in a strong covalent bond.
