Answer 2

Structural Formulas of Alkenes with the Composition C5H12 and their Names

The structural formulas of all the alkenes with the composition C5H12 are as follows:

1. Pent-1-ene: CH3-CH2-CH2-CH2-CH=CH2. 2. Pent-2-ene: CH3-CH2-CH=CH-CH3. 3. 2-Methylbut-1-ene: CH3-CH2-C(CH3)=CH2. 4. 2-Methylbut-2-ene: CH3-C(CH3)=CH-CH3. 5. 3-Methylbut-1-ene: CH3-CH(CH3)-CH2-CH=CH2. 6. 2,3-Dimethylbut-1-ene: CH3-C(CH3)=C(CH3)-CH2-CH3.

These are the six alkenes with the composition C5H12 and their corresponding structural formulas.

Please note that the numbering of the carbon atoms in the structural formulas follows the IUPAC nomenclature guidelines, where the double bond is assigned the lowest possible number.
