The diagrams show the structures of five hydrocarbons.
Which three hydrocarbons are isomers of each other?
A 1, 2 and 4 B 2, 3 and 5 C 2, 3 and 4 D 3, 4 and 5
Answer: A
Explaination
Isomers are those compounds that have same molecular formula but different structural formula.
Structures of option 1, 2 and 4 are same because of same number of C and H atoms (5C & 12H) means isomers of C5H12 which is pentane.
