Draw a Line Bond Structure for Propene (CH3CH=CH2): Indicate the Hybridization of Each Carbon and Predict the Value of Each Bond Angle

Propene, also known as propylene, has the chemical formula CH₃CH=CH₂. Below is the line bond structure for propene:

    H   H   H
    |   |   |
H—C—C=C—H
    |
    H

In this structure, the carbon atoms are connected as follows:

• The first carbon (C1) is bonded to three hydrogen atoms and one carbon atom (C2).
• The second carbon (C2) is bonded to two hydrogen atoms and two carbon atoms (C1 and C3).
• The third carbon (C3) is bonded to two hydrogen atoms and one carbon atom (C2).

Hybridization of Each Carbon:

• C1: This carbon is sp³ hybridized. It forms four sigma bonds with three hydrogen atoms and one carbon atom (C2).
• C2: This carbon is sp² hybridized. It forms three sigma bonds with two hydrogen atoms and one carbon atom (C1), and one pi bond with carbon atom (C3).
• C3: This carbon is sp² hybridized. It forms three sigma bonds with two hydrogen atoms and one carbon atom (C2), and one pi bond with carbon atom (C2).

Bond Angles:

• C1: The bond angles around this carbon are approximately 109.5°, typical for sp³ hybridized carbon.
• C2 and C3: The bond angles around these carbons are approximately 120°, typical for sp² hybridized carbon.

This structure and hybridization explain the geometry and bond angles in propene, making it a fundamental example in organic chemistry.
