Answer 2

Structural Formulas of Pentene-1, Hexene-2, Pentane, and Heptene-3

The structural formulas of organic compounds can be represented using line-angle or skeletal formulas. These formulas show the arrangement of atoms and the bonds between them. Here are the structural formulas for pentene-1, hexene-2, pentane, and heptene-3:

1. Pentene-1: CH3CH2CH=CH2. 2. Hexene-2: CH3CH2CH=CHCH2CH3. 3. Pentane: CH3CH2CH2CH2CH3. 4. Heptene-3: CH3CH2CH=CHCH2CH2CH3.

Please note that the numbers in the compound names indicate the position of the double bond in the carbon chain. For example, in pentene-1, the double bond is between the first and second carbon atoms.

I hope this helps! Let me know if you have any further questions.
