QUESTION:
Determine the molecular geometry of each molecule.
(a) \(C B r_{4}\)
(b) \(\mathrm{H}_{2} \mathrm{CO}\)
(c) \(C S_{2}\)
(d) \(\mathrm{BH}_{3}\)
ANSWER:
In order to predict the molecular geometry, we have to draw the Lewis structure of the given molecule and then molecular geometry can be predicted by VSEPR theory (steric number)
Steric number(SN) = (number of atoms bonded to central atom) +(number of lone pair on central atom)
Step 1 of 4
(a) \(\mathrm{CBr}_{4}\)
\({ }_{6} \mathrm{C} 1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{2}\) \({ }_{35} \mathrm{Br}[\mathrm{Ar}] 3 \mathrm{~d}^{10} 4 \mathrm{~s}^{2} 4 \mathrm{p}^{5}\)
Total number of valence electrons in \(\mathrm{CBr}_{4}=4+7(4)=32\)
Thus the Lewis structure is,
Now we will calculate the steric number (SN) = (number of atoms bonded to central atom) + (number of lone pair on central atom)
SN = 4 + 0 = 4
SN is 4 i.e the molecule has tetrahedral shape with bond angle \(109.5^{\circ}\), \(\mathrm{sp}^{3}\) hybridization.
