Question

Complete the following statements to demonstrate an understanding of the relationship between functional groups and isomers.

The two molecules above, which have  ____________  chemical formulas but different functional groups, are considered  ____________ .

The molecular formula for both molecules is  ____________ , although glyceraldehyde contains an oxygen double-bonded to  ____________ , while dihydroxyacetone contains an oxygen double-bonded to  ____________ .

Because of their minor differences in the arrangement of atoms, we would expect these two molecules to have  ____________  chemical properties and to  ____________  in chemical reactions.

Be unreactive

Identical

Similar

A central carbon

C6h12o6

Different

Isomers

C3h603

An end carbon

react differently

Isotopes

Answer 1

The two molecules above, which have same chemical formulas but different functional groups, are considered isomers .

The molecular formula for both molecules is same, although glyceraldehyde contains an oxygen double-bonded to an end carbon, while dihydroxyacetone contains an oxygen double-bonded to a central carbon .

Because of their minor differences in the arrangement of atoms, we would expect these two molecules to have different chemical properties and to ​​​​​​​react differently in chemical reactions.

Note -

Isotopes are those compounds which have same atomic number but different atomic mass. This is because the number of neutrons in these compounds is different.

Isobars are those compounds which have same atomic number but different mass number. This is because the number of protons in these compounds is different.

Isomers are those compounds which have same chemical on molecular formula but different structural formula because of presence of the different functional group or the arrangement of groups is different.
