Problem- When acetaldehyde is reacted is reacted with 3 equivalents of formaldehyde under alkaline condition, followed by treatment with sodium borphydride, the product formed show following spectra data IR:broad peak at 3326cm, HMR: singlet at 3.45 singlet at 4.78(found to be exchangeable)
I just need a general explanation of it please- Thanks!
Explain what is the wavelength of light emitted when an excited electron in hydrogen atom falls from the n=5 level to n=2? use nanometers
Copper can be drawn into thin wires. How many meters of 34-gauge wire (diameter = 6.304 x 10^-3 in.) can be produced from the copper in 6.95 lb of covellite, an ore of copper is 66.0% copper by mass
Before titrating with 0.2500M HCL the initial volume of acid in the buret is read as 2.08 mL. At the end point the final volume of acid in the buret is 25.20 mL. What is the concentration of the NaOH.
Problem- The NO molecule is a free radical, and the unpaired electron could be spin up (alpha) or spin down (Beta). This means that the electronic ground state has two degenerate states.
