There are two allotropes of carbon namely diamond an graphite It is non-sonorous It comprises of a dull appearance
(b) It is true that carbon is a versatile element due to which it is found in numerous chemical compounds. It can also form single, double and triple forms.
When connected to other carbon atoms, it forms chains as well as rings.
4 different chemical properties of carbon compound are as:
1) Combustion Reaction:
Carbon and carbon compounds gives carbon dioxide, vapor, heat and light on burning in air. Following are some of the examples of combustion reaction of organic compounds:
C + O2 ⇨ CO2 + Heat + Light
In combustion reaction, carbon compounds are oxidized in the presence of oxygen. The following example is different because alkaline KMnO4 is the oxidizing agent in this reaction.
CH3CH2OH + (Alkaline KMnO4/Acidified K2Cr2O7) ⇨ CH3COOH
3) Addition Reaction:
Formation of larger molecules by addition of more radicals is known as addition reaction. For example; ethene is converted into ethane when heated with the catalyst nickel.
CH2=CH2 + H2 + (Nickel catalyst) ⇨ CH3−CH3
4) Substitution Reaction:
Replacement of a functional group or any atom by another atom or functional group is known as substitution reaction. Substitution reactions are single displacement reactions.
When methane reacts with chlorine gas in the presence of sunlight, it gives chloromethane and hydrogen chloride.
CH4 + Cl2 + Sunlight ⇨ CH3Cl + HCl
all others are correct but only sources of energy doubt bcs for us they said there.
answer:covalent bonding in carbon compounds
Covalent compounds are the ones having strong intra-molecular bonds. This is because the atoms within the covalent molecules are very tightly held together. Each molecule is indeed quite separate and the force of attraction between the individual molecules in a covalent compound tends to be weak.
Physical properties of carbon compounds or organic compounds:Carbon compounds have low melting and boiling points because force of attraction between their molecules are not very strong. Carbon compounds are non- conductors of electricity because they do not contains ions. Most carbon compounds occur in all living things like plants and animals
Physical properties of covalent compounds:Covalent compounds are usually liquids or gases. Only some of them are solids. Covalent compounds are liquids and gases due to the weak force of attraction between their molecules. Covalent compounds have usually low melting and boiling points because only a small amount of heat energy is required to break the weak molecular forces. Covalent compounds are usually insoluble in water but they are soluble in organic solvents. Covalent compounds do not conduct electricity means they are non- electrolytes because they do not contains ions.
Carbon compounds are organic and covalent compounds. But it also should be noted that all carbon compounds are not organic. Example of non- organic carbon compounds are CO2, CaCO3, NaHCO3 etc.
bhadwav ha is ka answer
Carbon is a fascinating element. It is known to form almost ten million different compounds most of which are chemical compounds that are organic in nature. Let us learn a bit about the chemical properties of carbon compounds.
Explanation:In a combustion reaction, carbon compounds are oxidized in the presence of oxygenAlcohols undergo oxidation in presence of Oxidants like alkaline potassium permanganate (KMnO4) to form carbolic acids.Unsaturated organic compounds, like alkenes and alkynes, contain multiple bonds (C=C, C≡C) between their carbon atoms.They undergo addition reactions to become saturated in nature.Combustion of hydrocarbons may be of two types: Complete combustion and incomplete combustion.Complete combustion of hydrocarbons occurs in excess of oxygen(air), producing CO2 and H2O as the only final chemical products.Heat and light (clear blue flame) as a form of energy is generated.Incomplete combustion occurs when there is insufficient Oxygen(air) and the hydrocarbon is in excess.This reaction burns with a sooty or smokey flame and produces products which are CO(g) and/or C(s) and H2O.
