Question

complete the sentences to explain why the molecule ch3f is polar. match the words in the left column to the appropriate blanks in the sentences on the right.

Answer 1

CH3F is polar due to the electronegativity difference between C, H, and F, and because its tetrahedral geometry doesn't allow the polar bonds to cancel each other out, resulting in a net dipole moment.

Step-by-step explanation:

The molecule CH3F (fluoromethane) is polar because it contains a significant difference in electronegativity between the carbon (C), hydrogen (H), and fluorine (F) atoms. Fluorine is highly electronegative compared to hydrogen and carbon, which results in the electrons being pulled more towards the fluorine atom, creating a polar bond. Since the molecule is tetrahedral and the H-C bonds are slightly polar, while the C-F bond is significantly more polar, the overall geometry does not allow for the polarities to cancel out, leaving CH3F with a net dipole moment. Hence, the molecule is polar due to the presence of polar bonds and a non-symmetric distribution of those bonds.

Answer 2

The following words completes the sentences;

1) Tetrahedral

2) Different than

3) is not

A polar molecule is one in which the charge is distributed unevenly due to an asymmetric electron distribution. One portion of the molecule has a partial positive charge (δ+) and another part has a partial negative charge (δ-) due to the uneven distribution of electric charge.

When there is a large difference in the electronegativity of the atoms in the molecule, polar covalent bonds are formed, which causes the separation of charges.
