Question

Which among the following are structural isomers to each other?

• A.
• B.
• C.
• D.

Answer 1

Answer: (B), (C)

• Since there are 6 carbon atoms and 14 hydrogen atoms, the molecular formula of the first molecule is $C_6{H}_{14}$.
• Similarly, there are 6 carbon atoms and 14 hydrogen atoms in the second molecule, so, the molecular formula will be $C_6{H}_{14}$.
• In the third molecule, there are 5 carbon atoms and 12 hydrogen atoms, the molecular formula will be $C_5{H}_{12}$.
• In the fourth molecule, there are 4 carbon atoms and 8 hydrogen atoms, so, the molecular formula will be $C_4{H}_8$.
• The first and second molecules have the same molecular formula with different structures.
