Identify the types of intermolecular forces present in nh2nh2 and ch3ch3 and select the substance of the pair that has the higher boiling point.

Hi

Within a molecule, atoms are linked by intramolecular forces. These forces are those that must be overcome in order for a chemical change to occur. These forces determine the chemical properties of substances.

However, there are other intermolecular forces that act on different molecules or ions and make the sensors attract or repel each other. These are what determine the physical properties of substances. They are usually weak but their contribution is important.

In the exercise both substances exist London dispersion forces and dipole-dipole forces and hydrogen bridges in NH2NH2. The substance with the highest boiling point is NH2NH2.

Explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

a compound is a molecule made of atoms from different elements.
