D
Explanation
To determine the number of isomers for a given molecular formula, we can use the concept of structural isomerism. Structural isomers are molecules with the same molecular formula but different structural arrangements of atoms.
The given molecular formula is C?H??. Let's analyze the possibilities:
1. **Butane (straight-chain alkane):**
CH?-CH?-CH?-CH?
2. **Isobutane (branched alkane):**
(CH?)?-CH
These are the two possible structural isomers for C?H??. So, there are 2 isomers in total.
