Explain how you would distinguish the compounds within each set by a simple chemical test with readily observable results, such as solubility in acid or base, evolution of a gas, and so forth. (a) N-methylhexanamide; 1-octanamine; N,N- dimethyl-1-hexanamine (b) p-methylaniline, benzylamine, p-cresol, anisole
Ch 11.2 intermolecular forces - gen much weaker than intramolec (ionic, metallic, covalent bonds) - less energy required to vap liq / melt solid - van der Waals forces: dispersion forces & dipole-dipole attractions - ion-dipole ~ important in solutions - why weaker than ionic bonds - electrostatic interactions get stronger as the mag of the charges increases; weaker as distance btwn charges incr - dist btwn molecules often much greater than dist btwn atoms held together by chem bonds - dispersion forces - elec inter btwn electrically neutral, nonpolar atoms &/or molecules - motions of e- in atom/molec can create an instantaneous/momentary dipole Solvent ~ greatest amt Solutes ~ all other Solution formed when one substance disperses uniformly throug
