Account for the fact that treatment of $tert$-butyl methyl ether with a limited amount of concentrated HI gives methanol and $tert$-butyl iodide rather than methyl iodide and $tert$-butyl alcohol.

Write a condensed structural formula for, and assign an IUPAC name to, each of the following alcohols. a. Butyl alcohol b. Hexyl alcohol c. Isopropyl alcohol d. tert-Butyl alcohol

Why does Brutus think he must commit suicide?

Combustion analysis of $0.1500 \mathrm{~g}$ of methyl tert-butyl ether, an octane booster used in gasoline, gave $0.3744 \mathrm{~g}$ of $\mathrm{CO}_2$ and $0.1838 \mathrm{~g}$ of $\mathrm{H}_2 \mathrm{O}$. When a flask having a volume of $1.00 \mathrm{~L}$ was evacuated and then filled with methyl tert-butyl ether vapor at a pressure of $100.0 \mathrm{kPa}$ and a temperature of $54.8^{\circ} \mathrm{C}$, the mass of the flask increased by $3.233 \mathrm{~g}$.

(b) What is the molecular weight and molecular formula of methyl tert-butyl ether?
(c) Write a balanced equation for the combustion reaction.
(d) The enthalpy of combustion for methyl tert-butyl ether is $\Delta H^{\circ}$ combustion $=-3368.7 \mathrm{~kJ} / \mathrm{mol}$. What is its standard enthalpy of formation, $\Delta H_{\mathrm{f}}^{\circ}$ ?

Methyl tert-butyl ether 1MTBE2, or 2-methoxy-2-methylpropane, has been used as a fuel additive for gasoline to boost the octane rating and to reduce CO emissions.

c. Write the balanced chemical equation for the complete combustion of MTBE.

(a) Chromic acid oxidation of 4-tert-butyl-1,2- dimethylbenzene yielded a single compound having the molecular formula $\mathrm{C}_{12} \mathrm{H}_{14} \mathrm{O}_{4}$. What was this compound? (b) What product is expected from chromic acid oxidation of 2,3-dihydroindene?

Explain how Fick's first law arises from considerations of the flux of molecules due to a concentration gradient in a perfect gas.

Butylated hydroxytoluene (BHT) is a common preservative added to cereals and other dry foods. Its systematic name is 1-hydroxy-2,6-di-tert-butyl-4-methylbenzene (where "tert-butyl" is 1,1-dimethylethyl). Draw the structure of BHT.

Use formula (1) for simple interest to find each of the indicated quantities. $I=\$ 48 ; P=\$ 600 ; t=240$ days; $r=?$

Find the zeros of the function algebraically. ƒ(x) = 3x³-x²-2x

A chemist is planning to synthesize 3-octyne by adding 1-bromobutane to the product obtained from the reaction of 1-butyne with sodium amide. Unfortunately, however, he forgot to order 1-butyne. How else can he prepare 3-octyne?

In isosceles $\triangle \mathrm { ABC } , c = 15 \mathrm { cm } , a = 11 \mathrm { cm }$ and $\angle B = 68.5 ^ { \circ }$ Can this triangle be solved using the sine law? If so, solve it and explain your reasoning. If not, explain why not.
