Draw all the structural isomers for the molecular formula C4H9Br. Be careful not to draw any structures by crossing one line over another; the system needs to know where you intend connections to be between atoms. I came up with 4 different structures however still getting it wrong
Molecule with 3 single bonds and 1 lone pair of electrons around the central atom is predicted to have what type of molecular geometry? d. which of the following molecules is polar? PBr5, CCl4, BrF5, XeF2, XeF4 e. a sp3d hybridized central atom ha..
if a gas 25.0 c occies 3.60 liters at pressure of 1.00 atm, what will be its volume at a pressure of 2.50 atm
Draw the Lewis structure and structural formulas for CCl3F. Sketch the spacefiling model and the charge-density model for this molecule.
Water at 0 degrees C was placed inside a vessel maintained at low pressure by a vacuum pump. After some of the water evaporated, the remainder froze. If 1.2g of water evaporated, how much ice was obtained? Use the heats of vaporization and fusion ..
Draw the mechanism of the diel-alder reaction of 1,3-butadiene with maleic anhydride. Does the product have
A 4.82-L sample of carbon monoxide is collected at 55°C and 0.833 atm. What volume will the gas occupy at 1.05 atm and 25°C?
Name a compound with the formula, C5H12, which will show only one peak in the NMR spectrum.
After you have made your observations, you can release the vacuum and allow the pressure inside to return to atmospheric pressure. Do this by removing the pumper and squeezing the rubber septum as indicated.
