Molecular Structure of 1,3-Dichloropropane

,3-Dichloropropane is an organic compound with the molecular formula C3H6Cl2. It is a colorless liquid with a boiling point of 117 °C. The molecule has a linear shape with a central carbon atom bonded to two chlorine atoms and two hydrogen atoms.

The two carbon atoms at the ends of the molecule are each bonded to one hydrogen atom and one chlorine atom.The molecular geometry of 1,3-dichloropropane can be described using valence shell electron pair repulsion (VSEPR) theory. The central carbon atom has four electron pairs around it, two from the C-H bonds and two from the C-Cl bonds.

This gives the carbon atom a tetrahedral electron geometry. However, the two chlorine atoms are larger than the hydrogen atoms, so they exert a greater repulsive force on the electron pairs. This causes the tetrahedral electron geometry to be distorted into a trigonal pyramidal shape.The

bond angles in 1,3-dichloropropane are not all equal. The C-C-C bond angle is 112.2°, the C-C-H bond angles are 109.5°, and the C-C-Cl bond angles are 107.3°. The bond lengths in 1,3-dichloropropane are also not all equal. The C-C bond length is 1.54 Å, the C-H bond lengths are 1.10 Å, and the C-Cl bond lengths are 1.76 Å.
