Suppose a student measures out his cyclohexane according to step 3. He then allows the cyclohexane to sit at room temperature for 20 minutes before continuing to step 4. As a result of his technique error here, will the molecular weight he determines for naphthalene be higher or lower than the true value

Ametal with a large number of free flowing electrons most likely has good conductivity

Answer(d) unstable compounds that convert to acetals in the presence of alcohol and an acid; (b) semiacetals produced by alcohol subtraction from ketone;

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
