Show the structures of all possible acid-catalyzed dehydration products of the following. If more than one alkene is possible, predict which one will be formed in the largest amount: a. 2-methyl-2-butanol b. 1-methylcyclohexanol
Draw the structure of the major product(s) formed when 1-hexyne is subjected to ozonolysis, followed by hydrolysis.
determine the heat released when (ethene) CH2 CH2 reacts with hydrogen gas and form CH3CH3.If Bond enthalpies given are H H : 436 kJ/mol,C Br : 276 kJ/mol,C C : 612 kJ/mol,C C : 348 kJ/mol,C H : 412 kJ/mol;
How does one predict the regiochemistry of the products of aromatic reactions like nitration? What factors are responsible for the product ratios seen in such reactions?
A 500.0 g sample of aluminium is initially at 25.0 °C. It absorbs 32.60 kJ of heat from its surroundings. What is its final temperature, in °C? (specific heat = 0.9930 J g-1 K-1 for aluminum)
Explain why the boiling point of an aqueous solution that is 1.0 m in glucose (C6H12O6) is 100.51oC whereas The boiling point of an aqueous solution that is 1.0 m in NaCl is 101.02 oC .
Dry ice (solid CO2 ) has occasionally been used as an "explosive" in mining. A hole is drilled, dry ice and a small amount of gunpowder are placed in the hole, a fuse is added, and the hole is plugged.
Determine number of moles of oxygen molecules are in the cylinder and compute the mass of solid C 2 H 3 NaO 2 required mixing with 60.0mL of .125M C 2 H 4 O 2 to form a ph 4.20 buffer?
One beaker contains 10.0 mL of acetic acid/sodium acetate buffer at maximum buffer capacity (equal concentrations of acetic acid and sodium acetate), and another contains 10.0 mL of pure water.
The electron in the n = 5 level of a hydrogen atom emits a photon with a wavelength of 1280 nm. To what energy level does the electron move?
A balloon is filled to a volume of 7.00 x 102 mL at a temperature of 20.0 oC. The balloon is then cooled at constant pressure to a temperature of 1.00 x 102 K.
When 228.4 mg of pure X was burned 627.4 mg of CO2 and 171.2 mg of H2O were obtained. Determine the simplest formula of the compound X.
