Question

Select the Newman projection that corresponds to the following molecule 2. Select the choice that best describes the relationship of the following pair of compounds

Answer 1

The relationship of a pair of compounds could be one between these options : 
- Structural isomerisms
happened when molecules with same molecular formula have bonded together in different orders
- Stereoisomerism
Happened when two or more compounds differing only in the spatial arrangement of their atom

hope this helps

Answer 2

Both compounds have cis-trans geometry isomers

Both carbon compounds have a double bond and both carbon atoms bind two different groups

Further explanation

Isomers are two compounds that have the same chemical formula but different structural formulas

There is a grouping of isomers in Hydrocarbons:

• 1. Isomer structure consists of skeletal isomers, position isomers, and function isomers

• 2. Stereoisomers consist of geometric isomers and optical isomers

Geometric isomers occur because of differences in the direction of the groups in the molecule

geometrical isomers are found in compounds that have double bonds such as alkenes and the two atoms bind 2 different groups, so that if the location of the groups is exchanged the shape becomes different

If a similar group is located on the same side of the double bond it is called -cis, but if the group is opposite it is called -trans

Example:

Atomicity to 2 butenes. Where in cis-2 butene, both methyl groups are located on the same side whereas, in trans-2 butene, both methyl groups are opposite

The difference in the structure of the two compounds results in differences in physical properties such as the boiling point

The greater the number of carbon atoms making up it, the more the number of isomers
