Question

What are the names of the isomers for ${C_4}{H_8}B{r_2}$?

Answer 1

Hint: Isomers are molecules with identical molecular formulas — that is, the same number of atoms of each element — but distinct arrangements of atoms in space.

Complete answer:
Isomers are known as molecules that have similar molecular formulas. Isomers may vary in physical and chemical properties. This molecule contains four atoms of carbon, eight atoms of hydrogen and two atoms of bromine.

${C_4}{H_8}B{r_2}$ has $9$ isomers that are named as $1,4 - $ dibromobutane, $1,3 - $dibromobutane, $1$ ,$3$$ - $dibromo $ - 2 - $methylpropane, $1,2 - $dibromobutane, $1$$,2 - $dibromo$ - 2 - $methylpropane, $2,3 - $ -dibromobutane, $1,1 - $ dibromobutane, $2,2 - $dibromobutane, $1,1 - $dibromo$ - 2 - $methylpropane.

Note: Carbon is an element that is a part of the periodic table. It is a non-metal that can make covalent bonds. Its atomic number is six and molecular mass is taken as $12$. Carbon exists in various forms like coal, graphite and diamond. They are known as the allotropes of carbon.

The atomic mass of carbon: $12$$u$
The atomic mass of hydrogen: $1$$u$
The atomic mass of bromine: $79u$

Hydrogen is the first element of the periodic table and due to its properties, it is considered as both a metal and a non-metal. Hydrogen shows the properties of both a metal and a non - metal. Bromine is an element present in the periodic table whose atomic number is $35$ and the atomic mass is $79u$.
