Concept explainers
(a)
Interpretation:
The state of dibromomethane existing at − 75 C0 needs to be calculated.
Concept Introduction:
Heating curve is the representation of the changing in the state of substance from solid to liquid to vapor corresponding to different temperature.
The given substance dibromomethane usually exists at 3 states such as solid, liquid and vapor state. Each state of dibromomethane corresponds to different temperature like at temperature below − 53 C0 it exists at solid state.
At temperature above − 53 C0 it exists at liquid state while at temperature above 97 C0 it exists at vapor state.
While the − 53C0 and 97 C0 corresponds to freezing and boiling temperature of water.
(b)

- These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ? H Harrow_forwardQ5: Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Clearly show stereochemistry by drawing the wedge-and-dashed bonds.
