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.
What group of organic molecules does not dissolve in water?
A substance that doesn't mix with water is a hydrophobic substance. Common examples would be cooking oil, gasoline, petroleum jelly and wax.
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.
Detergent molecules are phospholipidlike molecules with highly polar heads and nonpolar tails Why is it a good idea to wear rubber gloves when washing dishes using detergents?
Dont use the interwebs to do your grade 12 bio homeowrk. Do it yourself. I know who you are and you get a zero. Go back and read the chapter pages 50-56,
What is the nature of covalent bond in alkanes?
Nonpolar. Good luck on the e2020 :)
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?
Fat molecules. Water molecule is polar, and therefore water is a good solvent for other polar molecules, dissolving them when they come in contact with one another. Water is not a good solvent for nonpolar molecules, such as fats. A fat has no polar grups to interact with water molecules. An emulsifier, however, can cause a fat to disperse in water. An emulsifier contains molecules with both polar and nonpolar ends. When the nonpolar ends interact with the fat and the polar ends interact with the water molecule, the fat disperses in water, and an emulsion results.
Why is carbon such a good element for organic molecules?
Carbon is a good element for organic molecules because of its incredible versatility, which derives from the arrangement of its valence electrons and the type and energy level of the bonds they form.
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.

Why is water not a good solvent for lipids?
Water molecules are polar, which means the oxygen side of the molecule is more negative, and the hydrogen side is more positive. Lipids are non polar, which means that one side is not more negative than the other. This is why no nonpolar substances dissolve in polar liquids
What are good solvents for lipids?
Non-polar organic solvents such as detergents (i.e. soap, which is just a salt of fatty acids, and other surfactants), and more powerful chemical solvents such as benzene, chloroform, diethyl ether, or hexane.

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 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.
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.
