Among the given atomic mass , the atomic mass of element X should be determined having molecular formula XF 3 and contains 65% F by mass. Concept introduction: Number of moles is equal to the ratio of given mass to the molar mass. The mathematical expression is given by: Number of moles = Given mass Molar mass Molar mass of the molecule is equal to the sum of the masses of atoms present in the molecule. Mass percentage is defined as the ratio of mass of the element to the total mass of compound or sample and multiplies by 100. The mathematical expression is given by: Mass percentage = Mass of element Total mass of compound ×100

Solution Summary: The author explains that the atomic mass of element X should be determined having molecular formula XF_ 3.
Among the given atomic mass, the atomic mass of element X should be determined having molecular formula XF3 and contains 65% F by mass.
Concept introduction:
Number of moles is equal to the ratio of given mass to the molar mass.
The mathematical expression is given by:
Number of moles = Given massMolar mass
Molar mass of the molecule is equal to the sum of the masses of atoms present in the molecule.
Mass percentage is defined as the ratio of mass of the element to the total mass of compound or sample and multiplies by 100. The mathematical expression is given by:
Mass percentage = Mass of elementTotal mass of compound×100
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!

Q5: Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Clearly show
stereochemistry by drawing the wedge-and-dashed bonds. Describe the relationship
between each pair of the stereoisomers you have drawn.
Classify each pair of molecules according to whether or not they can participate in hydrogen bonding with one another.
Participate in hydrogen bonding
