Answer
Isomers of A: B, C, D and F.
Identical to A: E
Work Step by Step
1. Compound A has 5 C's in a row, and a two-carbon branch on the 2º carbon.
2. All the compounds have the same amount of C and H atoms, therefore they can only be identical or isomers.
- B has 6 C's in a row: Isomer
- C has 6 C's in a row: Isomer
- D has 6 C's in a row: Isomer
- E has 5 C's in a row and a two-carbon branch on the 2º carbon: Identical
- F has 7 C's in a row: Isomer
