What intermolecular forces does propane have?

What intermolecular forces does propane have?

a) (i) The only intermolecular forces in propane are van der Waals dispersion forces. Because propane is a small molecule, these forces are also small, and so not much energy is needed to break them. At room temperature the molecules have too much energy for these weak forces to hold them together as a liquid.

What intermolecular forces does ch2o have?

The structure involves a central carbon doubly bonded to an oxygen atom and singly bonded to two hydrogen atoms. The C-O bond is a polar bond since oxygen is much more electronegative than carbon. This makes the molecule polar so dipole-dipole interactions are possible for the compound.

Does propane have dipole-dipole?

As a result, the propane molecule will be nonpolar, since no separation of charge will exist, i.e. the molecule has no permanent dipole moment. The direct consequence is that it only exhibits weak London dispersion forces, also known as Van der Waals interactions.

Is butane a dipole-dipole?

Butane is a non-polar molecule therefore it has London dispersion forces between molecules. These are the weakest type of intermolecular force, therefore it has the lowest boiling point. bond) therefore it has dipole-dipole forces between molecules.

Where is the phosphodiester bond in DNA?

In DNA and RNA, the phosphodiester bond is the linkage between the 3′ carbon atom of one sugar molecule and the 5′ carbon atom of another, deoxyribose in DNA and ribose in RNA. Strong covalent bonds form between the phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds.

What kind of bond holds the two strands of DNA together?

Covalent bonds occur within each linear strand and strongly bond the bases, sugars, and phosphate groups (both within each component and between components). Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.

What are the two strands of DNA?

The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), and thymine (T).
