What group of organic molecules does not dissolve in water?
Lipids, such as fats and oils, do not dissolve in water because they are nonpolar molecules. Water is a polar molecule, and oil is nonpolar, so they are not compatible and do not mix. This property of lipids is essential for their function in the body, such as forming cell membranes and storing energy.
Why are most organic compounds insoluble in water?
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.
Are non-polar molecules hydrophilic?
No, non-polar molecules are hydrophobic because they cannot form hydrogen bonds. A good example of this would be a cell membrane. The fatty acids in the lipid bilayer are non-polar and hydrophobic, while the polar ends that face the outside and inside of the cell are hydrophilic.
Why iodine dissolves readily in tetrachloromethane?
Both iodine and tetrachloromethane are nonpolar and aprotic solvents.therefore they can mix together and iodne is dissolved in tetrachloromethane and changes its colour from brown to purple.
Why is diethyl ether a food solvent for fats?
Diethyl ether is a good solvent for fats because it is a nonpolar solvent, meaning it can dissolve nonpolar substances like fats. Fats are hydrophobic molecules, and diethyl ether does not form hydrogen bonds with water, making it an effective solvent for extracting fats from food samples.
What are Nonpolar organic molecules are good examples of?
Hydrophobic compounds

What type of organic molecule requires the action of emulsifiers to be sucessfully digested?
Lipids, such as fats and oils, require the action of emulsifiers for successful digestion. Emulsifiers help to break down the lipids into smaller droplets, allowing digestive enzymes to access and digest them more efficiently.
How are the building blocks of organic molecules like brick?
The building blocks of organic molecules are like bricks because they are the foundation. Basic organic molecules are similar to bricks because you need them to build upon.

Is toluene a conductor?
No, toluene is not a conductor of electricity. Toluene is a nonpolar organic solvent that does not contain free ions or electrons necessary for conducting electricity.
Are halogens soluble in organic solvent?
Yes, halogens such as chlorine, bromine, and iodine are typically soluble in organic solvents due to their nonpolar nature. This makes them good candidates for extraction and purification processes in organic chemistry. However, the solubility can vary depending on the specific halogen and solvent being used.
What are some good examples of organic foods with future potential?
Organic foods with future potential include almost all fruits and vegetables. Organic baby foods are especially desirable, as mothers are increasingly turning to organic producers to feed their babies.
Why is carbon such a good element for organic molecules?
Carbon is a good element for organic molecules because it can form strong covalent bonds with other carbon atoms and a variety of other elements. This allows for the formation of diverse and complex molecular structures, critical for the vast array of organic compounds found in living organisms. Additionally, carbon can form stable bonds with other elements like hydrogen, oxygen, nitrogen, and sulfur, enabling it to participate in a wide range of chemical reactions.
Why is alcohol misible in water?
Alcohol is miscible in water because they both have similar properties.A good rule of thumb is "like dissolves like"For example, water, which consists of polar molecules, is not miscible in oil, because oil consists of nonpolar hydrocarbon chain molecules.
Chemistry Required For Biomedical Engineering?
A good background in inorganic and organic chemistry is required for biomedical engineering. After accomplishing study in inorganic chemistry, one must obtain a solid understanding of how organic carbon and other molecules comprise the essential structures of life molecules. Organic chemistry enables one to study the activities of different micro-bodies.
What characteristics do many organic compounds in common?
Most of the organic molecules have good bit of number of carbons in it.An organic molecule having carbon, Hydrogen and oxygen is called ether.An organic molecule having carbon, hydrogen and Nitrogen is called amines.All organic compounds have carbon and hydrogen in them, the compound needs both carbon and hydrogen to be organic.
