dipole-dipole vs induced dipole

[Ayush Ray 1I]

What exactly is an induced dipole and what is the difference between an induced dipole and dipole-dipole?

[Ami_Pant_4G]

Dipole-dipole bonds depend on the polarity of molecules where as dipole-induced dipole bonds (aka van der waals forces) depend of the polarizability of electron clouds. hope this helps:)

[William Francis 2E]

Permanent dipoles exist in polar molecules. When oppositely charged dipoles attract between molecules, it is called a dipole-dipole force. Induced dipoles are temporary and present in nonpolar molecules when electrons unevenly distribute charge. These are Van Der Waal's forces.

[Michelle N - 2C]

A dipole-dipole interaction is when two molecules with partial charges are in contact there.

Dipole-induced dipole is when there is a dipole (a molecule with a partial charge) next to an induced dipole (an atom/molecule) without a charge). If it gets close enough, the partial charge on the diple would then cause the nonpolar molecule's electrons to shift, making that once no charge molecule, a charged molecule.

[Jocelyn Thorp 1A]

induced dipole= van der waal's forces= london forces, right?

[Miriam Villarreal 1J]

dipole dipole occurs between polar molecules (partial negative and partial positive) while induced dipole attraction is a weak attraction that results when a polar molecule induces a dipole in an atom or in a nonpolar molecule by disturbing the arrangement of electrons in the nonpolar species. (therefore at any given time one end of a molecule may be more negative than the other.)

induced dipole= van der waal's forces= london forces, right?

not exactly
all bonds have some sort of van der waal's forces/london forces however, induced dipole is when the charge/polarity of a polar molecule causes a nonpolar molecule to have an instantaneous dipole.

van der waals/london forces are when two nonpolar molecules have random instantaneous and very weak dipoles

[ValerieChavarin 4F]

Dipole-dipole interactions occur in polar molecules, while an induced dipole has to do with the uneven distribution of charges, resulting form a shift in electrons.

[Natalie Benitez 1E]

Why is the molecule OCS is considered polar,shouldn't their dipoles cancel out making the molecule non-polar?

[Amanda Mei 1B]

Why is the molecule OCS is considered polar,shouldn't their dipoles cancel out making the molecule non-polar?

Oxygen is more electronegative than sulfur, which means the C-S bond will have a stronger partial negative charge on the sulfur and the C-O bond will have a weaker partial negative charge on the O. Although the molecular is arranged symmetrically, the dipole aren't identical so they don't cancel out, resulting in the molecule being polar.
