Compute Mass of Each Element. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in CHCl3: Molar Mass (g/mol) C (Carbon) 1 × 12.0107 = 12.0107. H (Hydrogen) 1 × 1.00794 = 1.00794. Cl (Chlorine)Step 1: Find the central atom: Usually, single-atom with the least electronegativity becomes the central atom. In the case of CH3Cl, there are only two single atoms C and Cl, where their electronegativity values are 2.6 and 3.2. As the Carbon (C) atom has a lower value, so it will be the central atom. Step 2: Figure out the total number of ...

Does chloroform have a greater dipole because the $\\ce{C-H}$ dipole is weaker than $\\ce{C-Cl}$ dipole thereby making the overall net dipole greater in chloroform, as opposed to trichlorofluoromethaneExpert Answer. 49. BeF2 has the largest bond angle as it is linear in structure and the value is 180o. On the other hand bond angle of S-O-S in SO4- is 109.5° (tetrahedral molecular), Cl-C-Cl is HCCl3 is 109.5° (tetrahedral), and H-O-H in H2O 104.5o (Its electron p …. View the full answer.
