Predict which substance in each of the following pairs would have the greater intermolecular forces co 2 or ocs ch 3 ch 2 ch 2 nh 2 or h 2 nch 2 ch 2 nh 2

OCS

H2NCH2CH2NH2

Explanation:

The intermolecular forces are the forces that join together the molecules in a substance. There're three types of it:

1. CO2 is a linear molecule that has two C=O bonds. These bonds are polar (C and O have differents electronegativities), but the dipole moment is canceled, and equal to 0, thus it's a nonpolar molecule, and has dipole induced - dipole induced force.

OCS is linear too, but the moment is not 0, because the polarity of the C=O is higher than the polarity of C=S, thus the molecule is polar, and the force is dipole-dipole. So, OCS has a greater intermolecular force.

2. CH3CH2CH2NH2 is a polar molecule that has the hydrogen bond as intermolecular force (H is bonded to N). But it also has a dipole induced -dipole induced force at the other part of the molecule.

H2NCH2CH2NH2 has hydrogen bonds on both sides of the molecules, thus, it has the strongest force.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
