In contrast to intramolecular forces, such as the covalent bonds that hold atoms together in molecules and polyatomic ions, intermolecular forces hold molecules together in a liquid or solid.Intermolecular forces are generally much weaker than …Which is a protic solvent? A CCl4 B HCCl3 C CH3OH D CH3CH24CH3 E CH3CH2OCH2CH3.

This value is less than 0.4, which indicates that the bond between Carbon (C) and Hydrogen (H) is nonpolar. Hence, each C-H bond is a nonpolar covalent bond. For C-Cl bond; The electronegativity difference (ΔEN) = 3.16 - 2.55 = 0.61. This value lies between 0.4 to 1.7, which indicates that the bond between Carbon (C) and Chlorine (Cl) is polar.

FC= V - (N + B) Where: V - number of valence electrons. N - number of nonbonding electrons. B - number of bonds. Notice that this is not the only formula for calculating the formal charge, however, I figured it was the best variation acceptable to my students.

The predicted rate law for the given three-step mechanism is: Rate = k[Cl][CHCl3]. To determine the predicted rate law for the given three-step mechanism, we need to examine the rate-determining step.The predicted rate law for the given three-step mechanism is: Rate = k[Cl][CHCl3]. To determine the predicted rate law for the given three-step mechanism, we need to examine the rate-determining step.

Dipole moment = Partial charge on atom * Bond length. Even though F is more electronegative, CH3Cl has greater dipole moment because the bond length in this case is far longer than that in the case of CH3F since F is highly electronegative and it attracts the electron pair very strongly. Dipole moment is not just about charge, it is the product ...
