The correct answer is; Carbon atoms can form chains and branches with each other, and other atoms can attach to these.

Organic chemistry is regarded as the chemistry of carbon compounds and carbon atoms are known to catenate.

Organic chemistry is the branch of chemistry that studies carbon compounds. There are thousands of organic compounds in existence.

The common thread that joins all these organic compounds is that they all contain a long or branched chain of carbon atoms linked to each other. This ability of carbon atoms to self-link forming long chains or branches or macrocyclic compounds is called catenation.

The long or branched chain of carbon is therefore the "back bone" or main framework of the compound.

Answer:

(Question 1) Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible?

(Answer) The bonds can shift because valence electrons are held loosely and move freely.

(Question 2) Between which types of elements do ionic bonds occur, and how do electrons act within the bond?

(Answer) metals and nonmetals, electrons transferred

(Question 3) Which kind of bond would occur between sodium (Na, Group IA) and chlorine (Cl, Group VIIA)?

(Answer) ionic

(Question 4) Why is carbon said to provide a “backbone” in many molecules?

(Answer) Carbon atoms can form chains and branches with each other, and other atoms can attach to these.

Hello

please make sure that there is any group which is join with alkane

there should be less liquid at the end of the experiment since heating liquid is an endothermic process, and endothermic processes typically break the bonds between liquids. The applied heat would soon break the bonds that hold the molecules of the liquid together, and evaporation would occur once the temperature is hot enough. Thus, the evaporated water would decrease the volume of the liquid.

Explanation:

To make a 2 M solution, the correct method is to dissolve 1 mole of the compound in 2 L of water. This results in a concentration of 2 moles per liter, which corresponds to a 2 M solution.

The correct option is C.

To make a 2 M (molar) solution of a compound, we need to dissolve an appropriate amount of the compound in a given volume of solvent, typically water, to achieve a concentration of 2 moles per liter.

Molarity (M) is defined as moles of solute per liter of solution. To prepare a 2 M solution, we need a concentration of 2 moles per liter. This means that for every liter of solution, we should have 2 moles of the compound.

Option A suggests dissolving 1 molar mass of the compound in 2 L of water. However, molar mass is not equal to moles. Molar mass represents the mass of one mole of the compound.

Option B suggests dissolving 2 moles of the compound in 1 L of water. This would result in a concentration of 2 moles per liter, which matches the desired 2 M concentration. However, the given option indicates dissolving 2 moles in 1 L, which contradicts the definition of molarity.

Option C suggests dissolving 1 mole of the compound in 2 L of water. This aligns with the definition of molarity, as it gives us a concentration of 1 mole per liter. To achieve the desired 2 M concentration, we would need to double the amount, resulting in 2 moles per liter.

Option D suggests dissolving 2 g of the compound in 1 L of water. This option does not consider the molar mass of the compound and assumes that the molar mass is equal to 2 grams per mole, which is not always the case.

In conclusion, option C is the correct choice for making a 2 M solution, as it involves dissolving 1 mole of the compound in 2 L of water.

Answer:

if wrong sorry ok????

Alkynes are called the hydrocarbons. Ethyne is an important alkyne which is used in oxyacetylene gas cutting. A hydrocarbon containing a carbon-carbon triple bond is the alkyne. The correct option is C.

In organic chemistry, an alkyne is defined as the unsaturated hydrocarbon containing at least one carbon-carbon triple bond. The alkynes are unsaturated hydrocarbons and their general formula is CₙH₂ₙ₋₂ and the triple bond is known as the acetylene bond.

Many alkynes are found in nature. Ethyne is the first member of the alkyne family in which two carbon atoms are connected by a triple bond. Almost all alkynes are also found to be hydrophobic in nature.

Alkynes show three types of isomerism like chain isomerism, position isomerism and functional isomerism. The triple bond present in the alkynes is its functional group.

Thus the correct option is C.
