Anything less that 7, would be a base.
Reaction of
Acyl Halides with
Grignard reagent results in the formation of
Ketones in first step. While in second step reaction of Grignard reagent with Ketones results in the formation of
Tertiary Alcohols.
If you want to
stop the reaction at
Ketone stage then you are required to use another
mild reactive organometallic compound. In our case we will use Organocuprates.
Organocuprates are also known as Gilman Reagents. These reagents does not add to ketones, aldehydes and esters but they can add to acid halides to produce Ketones.
Eutrophication results from an excess of
a. phosphates
Answer:
A. 3
Explanation:
Given
The atomic radius of Hydrogen rH = 53 pm
The atomic radius of Uranium rU = 156 pm
we apply
rU / rH = 156 pm / 53 pm
⇒ rU / rH = 2.943 ≈ 3
then
rU = 3*rH
