Question

decide whether each molecule or polyatomic ion is polar or nonpolar. if the molecule or polyatomic ion is polar, write the chemical symbol of the atom closest to the negative side. for example, if the molecule were hcl and you decided the hydrogen atom was closest to the negative side of the molecule, youd enter \h\ in the last column of the table. molecule or polyatomic ion polar or nonpolar? atom closest to negative side ocs polar nonpolar ch₃f polar nonpolar i₂ polar nonpolar

Explanation:

Step1: Analyze OCS

OCS is a linear molecule. Oxygen is more electronegative than carbon and sulfur. The dipole - moment does not cancel out, so it is polar. The most electronegative atom (O) is closest to the negative side.

Step2: Analyze CH₃F

In CH₃F, fluorine is highly electronegative. The molecule has a tetrahedral geometry, and the bond - dipoles do not cancel out, making it polar. Fluorine is the most electronegative atom, so it is closest to the negative side.

Step3: Analyze I₂

I₂ is a homonuclear diatomic molecule. The two iodine atoms have the same electronegativity, so the electron - density is evenly distributed, and the molecule is non - polar.

Answer:

molecule or polyatomic ion	polar or nonpolar?	atom closest to negative side
CH₃F	polar	F
I₂	nonpolar	N/A
