State the kind of intermolecular forces that would occur between the solute and solvent in acetic acid (polar, contains an OH group) solution

•London dispersion force

•dipole-dipole force

•hydrogen bonding

Explanation:

•London dispersion force: Because of movement of electrons around the atom, a temporary opposite poles are created at the end of a molecule. Therefore one side will be more negatively charged(because of presence of more electrons there) while other end will be positively charged hence creating a weak temporary attraction between the charged ends.

•Dipole-dipole interaction: this force is created due to electrostatic charge between positive end of one molecule of acetic acid and the negative end of another acetic acid molecule. The unshared pair of electrons on oxygen atoms makes it a negatively charged atom compared to other atoms in acetic acid molecule hence the ends with hydrogen will be more negatively charged.

•Hydrogen bonding: this interaction occurs between oxygen of one acetic acid molecule with the hydrogen of another acetic acid molecule,resulting in a temporary covalent bond.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
