Radio waves. Microwaves would cook the earth, seismic waves would just cause earthquakes everywhere, and infrared waves would also cook the earth.
Here we have to explain and get the product of the reaction between 3-methyl-1,3-diol and chromium-tri-oxide (CrO₃)
The reaction between 3-methyl-1,3-diol with chromium-tri-oxide (CrO₃) form 3-methyl-3-hydroxybutanal.
The CrO₃ is used as a mild oxidant to the alcohol. It only produces aldehyde or ketone depending upon the position of the -OH group in a secondary or primary alcohol.
Here we can see there are two hydroxy (-OH) group in the reactant. However one of the hydroxy is at terminal carbon atom, thus primary alcohol and other in between as tertiary alcohol.
As the reagent CrO₃ does not reacts on the tertiary -OH group thus the -OH group present at 3 position will not be oxidized. Thus only the terminal hydroxy group will oxidize to form the corresponding aldehyde.
Henceforth the final product of the reaction is 3-methyl-3-hydroxybutanal as shown in the figure.
Answer:
subtract the answer it'll get you that.
Explanation:
Answer:
c) he describes specific locaions for the electrons
Explanation:
he determined that electron are around the nucleus in fixed orbits where as Rutherford did not give any concept of orbits. the concept of orbits also explains the change in energy levels as the electron moves from higher to lower or lower to higher energy level.
