Isomers of C8H16 and their Semi-Structural Formulas

The molecular formula C8H16 represents a group of isomers known as alkanes. Alkanes are hydrocarbons that consist of only carbon and hydrogen atoms, with single bonds between the carbon atoms. In this case, we are looking for three isomers of C8H16. Let's explore their semi-structural formulas and provide their names:

1. 2,2,3-Trimethylpentane: - Semi-Structural Formula: CH3-CH(CH3)-CH(CH3)-CH2-CH2-CH2-CH3 - This isomer has a branched structure with three methyl (CH3) groups attached to the second carbon atom, resulting in the name "2,2,3-trimethylpentane" [[1]].

2. 2,4-Dimethylhexane: - Semi-Structural Formula: CH3-CH2-CH(CH3)-CH2-CH(CH3)-CH2-CH3 - This isomer also has a branched structure with two methyl (CH3) groups attached to the second and fourth carbon atoms, giving it the name "2,4-dimethylhexane" [[2]].

3. 3-Ethylpentane: - Semi-Structural Formula: CH3-CH2-CH2-CH2-CH(CH3)-CH2-CH3 - This isomer is a straight-chain alkane with an ethyl (CH2CH3) group attached to the third carbon atom, resulting in the name "3-ethylpentane" [[3]].

These are the semi-structural formulas and names of three isomers of C8H16.
