1) The molarity of naphthaline in a solution of naphthalene (C10H8, MW = 128.8), a non-ionizing and nonvolatile solute, and benzene (CH, MW = 78.11), a volatile solvent, is (C10Hg] =0.086 M. The density of the solution is D = 0.8748 g/cm. Find the following: a) The osmotic pressure exerted by the solution, at T = 25.0 °C. Give your final answer in units of torr. [8 points) b) Xn, the mole fraction of naphthalene in the solution. [15 points]
Please help! of naphthalene, C10H8), results in two products. One product is kinetically favored and predominates in the beginning of the reaction. Because the reaction is reversible, eventually the kinetically slower but thermodynamically favored product predominates. Draw the structure of these two products. (The naphthalene ring is already drawn for you. Do not change the double bond configuration in the given structures.)
A solution contains naphthalene (C10H8) dissolved in hexane (C6H14) at a concentration of 11.17 % naphthalene by mass. Calculate the vapor pressure at 25 ∘C of hexane above the solution. The vapor pressure of pure hexane at 25 ∘C is 151 torr. Express the answer using three significant figures.
Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 1.025 g of naphthalene is burned in a bomb calorimeter, the temperature rises from 24.25 ∘C to 32.33 ∘C. Find ΔErxn for the combustion of naphthalene. The heat capacity of the calorimeter, determined in a separate experiment, is 5.11kJ/∘C. Express the change in energy in kilojoules per mole to three significant figures.
6. (20 points) There are three non-equivalent resonance Lewis structures for the selenate ion, Se042. Draw the three non-equivalent (different formal charge distribution) resonance structures for the ion. Indicate the formal charges for all atoms in each resonance structure. Which structure is the major contributor to the resonance?
Draw the structures of the intermediate carbocations in the alkylation of naphthalene, the active ingredient of moth balls. Why does naphthalene undergo electrophilic substitution at C1 rather than C2? Draw resonance structure(s) to justify your statement.
Three resonance structures of the following structure are possible. One resonance form is given below. Draw the remaining resonance structures, in any order, including nonbonding electrons. Omit curved arrows.
