Alkanes are saturated compounds containing carbon and hydrogen only.
Structures 1, 2, 3 and 4 are saturated hydrocarbons.
Which pair of structures are isomers?
A 1 and 2 B 1 and 4 C 2 and 3 D 2 and 4
Answer: A
Explaination
First we will calculate total number of C and H atoms in the given structures.
Structures 1 and 2 are the isomers of each other as their number of C atoms and H atoms are same so they have same molecular formula but different structural formula.
