    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.
