Water molecules are attracted to each other with some very strong forces, like hydrogen bonding and dipole-dipole attractions. Those attractions lower the energy of the water molecules and make their interactions very favorable (which is why water has such a high melting and boiling point). To dissolve an organic molecule (or any molecule for that matter) into water, you need to physically separate these water molecules from each other to carve out space for the molecules to reside. This means breaking up some of these really favorable hydrogen bonding and dipole-dipole interactions. The only way this is going to happen is if the interactions the water molecules have with the organic molecules are as good if not better than the interactions the water molecules were having with each other. Those organic molecules that can form hydrogen bonds and/or are polar tend to be soluble in water because they can replace the nice interactions between the water molecules. Those organic molecules that are non-polar or are really big and partially non-polar will not be able to replace the happy water-water interactions and so will be excluded (i.e. sit in a layer on top of the water). Ironically, from an energy standpoint, the organic molecules would love to hang out with the water molecules and benefit from their strong dipoles, but just like nerds at a party full of "cool kids" are excluded from those interactions because they cannot reciprocate with a strong dipole of their own.
Organic compounds are typically nonpolar or have limited polarity, which makes them unable to form strong interactions with water molecules. This leads to poor solubility in water, as water is highly polar and tends to only dissolve other polar or ionic substances. Additionally, the presence of hydrophobic groups in organic compounds further reduces their ability to dissolve in water.
The solubility of a substance in water depends on whether its molecules are polar. Polar substances will dissolve more readily in water (which is a polar substance itself) than nonpolar substances will.
Many organic compounds, such as ethanol and lactic acid, are actually fully soluble in water.
But many others are not as they contain nonpolar hydrocarbon chains and nonpolar substances are generally insoluble in polar substances such as water.
ionic compounds are polar,only a polar solvent can dissole a polar compound,so salt will not dissolve in oil but will dissolve in water because water is polar.....

Is silicon dioxide soluble or insoluble?
Silicon dioxide, also known as silica, is insoluble in water and most organic solvents. However, it can react with strong alkaline solutions to form silicates, which are soluble.
Do organic compounds dissolve in water?
Some organic compounds can dissolve in water, while others do not. Solubility varies depending on the specific structure and properties of the organic compound. For example, simple organic molecules like alcohols and carboxylic acids tend to be soluble in water due to the presence of polar functional groups that can interact with water molecules through hydrogen bonding.
What are things that contain oxygen?
Air, water, plants, animals, rocks, minerals, and most organic compounds.
What two elements organic compounds always contain?
Organic compounds always contain carbon and hydrogen.
Which is most likely to contain organic compounds?
A compost heap or a garden soil would most likely contain organic compounds, as they are made up of decomposed plant and animal material that provide nutrients to plants.
What is true of most organic compounds?
Most organic compounds contain carbon atoms in their structure, are associated with living organisms, and often have covalent bonds.
Are organic compounds less soluble in water?
Organic compounds have to be defined as best as possible to determine what is soluble in water. Organic compounds are molecules composed with carbons--pure hydrocarbons like octane would not be soluble in water. Organic compounds can also have electronegative molecules in it. Dichloroethane, methanol, ethanol, etc are soluble in water. However, most organic compounds will more likely have low solubility in water, since increasing the number of carbon molecules in any compound drastically reduces water solubility.
Is water one of the most organic compounds for living things?
Water is vital but it is INORGANIC
What can you tell about methane (CH4) from its molecular formula?
It is a saturated hydrocarbon. It is a covalent compound and has all properties which are identical to simple covalent compounds. Low boiling and melting points, soluble in organic solvents (most simple covalent compounds are soluble in organic solvent), insoluble in water and does not conduct electricity as in does not have free ions.Its tetrahedral geometry makes it non-polar.It contains four hydrogen atoms
Are organic compounds made of sugars or starches.?
Sugars and starches are organic compounds. But not all organic compounds are sugars and starches .
Is silicon dioxide soluble or insoluble?
Silicon dioxide, also known as silica, is insoluble in water and most organic solvents. However, it can react with strong alkaline solutions to form silicates, which are soluble.
Most of the compounds that contain carbon are called?
organic chemistry.
Are most hydroxide compounds soluble in water?
Most hydroxide compounds are soluble in water. However, the solubility can vary depending on the specific hydroxide compound. Common hydroxide compounds like sodium hydroxide (NaOH) and potassium hydroxide (KOH) are highly soluble in water.
In which solvent Iron oxide is soluble?
Iron oxide is not soluble in water or organic solvents like ethanol or acetone. It is insoluble in most common solvents.
Why water is the most important?
Water has a polar molecule; this is the principal cause which favors the dissolution of hydrophilic compounds. Water is also a solvent for the most important organic compounds involved in biochemistry.
What most likely to contain organic compounds?
living things are most likely to contain organic compounds
Most hydroxide (OH) compounds are insoluble?
