Reaction of an Alcohol to Produce an Alkyl HalideN-butanol reacts with NaBr and H2SO4 to produce n-butyl bromide, via refluxation reaction in a lab experiment.
a) Why is an excess of sulphuric acid used?
b) Why is concentrated sulphuric acid is more effective than water in removing trace amounts of alcohol to form an alkyl halide?
c) What two other organic products may be formed during the reaction?
A weather balloon at Earth's surface has a volume of 3.9 L at 275 K and 775 mm Hg. if the balloon is released volume reaches 4.2 L at 711 mm Hg what is the temperature.
Ethylene glycol is used as automobile antifreeze. 6.38g og this compound contains 2.47g of carbon and 0.620g of hydrogen. The rest is oxygen. The molar mass is 62.0g/mole.
how many liters of o2 can be made from 342g H2o2 if the density of o2 is 1.428g.
