CO₂ does not have dipole-dipole forces as its strongest force.
Draw the 3D structures of each molecule. All have C-O, C-Br, or C-Cl <em>bond dipoles</em>.
In CO₂ the C-O bond dipoles point in opposite directions, so they cancel.
CO₂ has <em>no molecular dipole</em>. Its strongest intermolecular forces are <em>London dispersion forces</em>.
In all the other molecules, the C-Br, C-Cl, and C-O bond dipoles do not cancel. These molecules all have intermolecular dipole-dipole forces.
the temperature, internal energy and kinetic energy
Look that up on the Internet it will tell you
The correct answer is ''External''.

If Oxygen (O) lost 2 protons it would become Carbon (C).
