Diazene, N2H2 (also known as diimine), is commonly used as a reagent for organic syntheses. Label each image with the type of
Fittoniya [83]

The first image shown at the left hand side is a pi bond. The other two images show sigma bonds.

In chemistry, a bond results from the overlap of atomic orbitals. This overlap may be end to end (sigma bond) or side by side (pi bond). Having said this, it is easier to decide whether the bonds in the image shown are sigma or bi bonds.

If we label the images; 1,2,3 from left to right, we can see that the overlap in image 1 is side by side. The electron density lies above and below the plane of the bond. This is a pi bond. In images 2 and 3, the overlap occurs in an end to end manner. This is a sigma bond.

Identify whether each reaction represents a chemical reaction or a nuclear reaction by filling in the blank with the word ‘chemi
svetoff [14.1K]
Answer 1) Cl_{2} + H_{2} ----> 2 HCl 
This is a pure chemical reaction that is taking place.

In this reaction the two chemical species which are Chlorine and Hydrogen undergo addition reaction and form two moles of hydrochloric acid. No new species is formed except the combination of reactants which gives the product.

Answer 2) H + H ----> He + n
This is a nuclear reaction.

As the reactant species is undergoing a reaction which is resulting in formation of new species completely different than the elements in reactants. 

Also there is a neutron which is generated after the reaction this is clear indication of nuclear fusion reaction. Hence, it can be called as nuclear reaction.

Almost. treating an acyl chloride with a grignard reagent tends to form (via two steps) an alcohol. what reagent forms the keton
PIT_PIT [208]
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.
