Which substance below has dipole-dipole forces co2, ch4, h2s, f2?

Dipole moment is a vector quantity and is equal to charge multiplied by distance. When a molecule is symmetrical (repeat its face when rotated at 180°) then the dipole moments present in it will cancel out each other making the molecule non polar. In given examples,

CO₂ has zero dipole moment as it has linear structure and both dipoles cancel out each other.

CH₄ has a symmetrical Tetrahedral structure, it also cancel out all dipole moments making the molecule non polar with zero dipole moment.

H₂S has a bent structure and a dipole moment of 0.95 D. As the sulfur contains 2 lone pair of electrons, so lone pair of electrons contribute in dipole moment.

F₂ is also non polar and symmetrical, so the net dipole moment of this molecule is zero.

It dont even matter because at the end of thre day we gone life like it ius s
