There are 3 different possible structures (known as isomers) for a dibromoethene molecule, C2H2Br2. One of them has no net dipol
e moment, but the other two do. Draw a structure for each isomer. Include H atoms.

Explanation:
Compounds having same molecular formula but different structural and spatial arrangement are isomers.
Three isomers are possible for dibromomethene.
In one structure (IUPAC name: 1,1-dibromomethene), both the bromine atoms are attached to one carbon atom.
In another two structures (Cis and trans), two bromine atoms are attached to two different carbon atoms.
In Cis 1,2-dibromomethene, two bromine atoms are present on the same side.
Whereas in Cis 1,2-dibromomethene, two bromine atoms are present on the opposite side and hence, does not have net dipole moment.

Answer:
Smallest to biggest order is as follows.
C < O < Amino < Water < Glucose < Starch < protein.
Explanation:
The given atoms or molecules and their atomic masses is as follows.
Glucose - - 180 g/mol
Starch - - 692.7 g/mol
Protein - - it is vary for different proteins.
Carbon - C - 12 g/mol
Water - - 18 g/mol
Amino - - 17 g/mol
Oxygen - O - 16 g/mol
Increase the molar mass increases size of the molecules.
Therefore, Smallest to biggest order is as follows.
C < O < Amino < Water < Glucose < Starch < protein.
