Question

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

Answer 1

Answer:

OCS

H2NCH2CH2NH2

Explanation:

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

• Dipole induced - dipole induced --> It happens in the nonpolar molecules, which have dipole moment equal to 0. It's the weakest intermolecular force;
• Dipole - dipole --> It happens in polar molecules, which have dipole moment different from 0. It's the second strongest;
• Hydrogen bond --> It happens when hydrogen is bonded with a large electronegativity element (F, O, or N). It's the strongest.

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.

Answer 2

In the given pair of compounds, OCS and  $\rm H_2NCH_2CH_2NH_2$ has greater intermolecular force.

The intermolecular force has been the attraction force that has been present in the atoms in a molecule. The dipole-induced dipole intermolecular force has been the weakest force, while the hydrogen bond has been the strongest force.

In the given pair of compounds, carbon dioxide has dipole-induced dipole force, while OCS has dipole interactions.

Thus, OCS has a greater intermolecular force.

$\rm CH_3CH_2CH_2NH_2$ has been consisted of the dipole induced -dipole force, while  $\rm H_2NCH_2CH_2NH_2$ has been consisted of the hydrogen bonding in the molecule, Thus, $\rm H_2NCH_2CH_2NH_2$ has greater intermolecular force.
