Question 1 what is the strongest attractive force between a molecule of benzophenone and a molecule of hexane? dipole/dipole interactions london dispersion forces lonic bonding hydrogen bonding dipole/ion interactions

Hydrogen bonding

Explanation:

The molecule of benzophenone (in the picture below) is polar because it has a bond of carbon and oxygen and these elements have huge differences of electronegativity, so they'll have partial charges: oxygen will be with negative partial charge because it has higher electronegativity (it attracts the electrons better).

The molecule of hexane (in the picture below) only has bonds between carbon and hydrogen which have close electronegativity, so the molecule is nonpolar. But, it can form an induced dipole, and the hydrogen will have a partial positive charge for a moment.

When these two molecules approach, the hydrogen and the oxygen must form a bond, which is called hydrogen bonding, and always occurs between hydrogen and an atom with high electronegativity (N, O, and F).

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
