Identify the correct statement regarding geometry and lone pair of electrons present in CH ₄ and SiCl ₄
Options
- ABoth have same geometry with two lone pair of electrons each.
- BBoth have different geometry with one lone pair of electrons each.
- CBoth have same geometry with no lone pair of electrons each.
- DBoth have different geometry with no lone pair of electrons each.
Correct answer
C. Both have same geometry with no lone pair of electrons each.
Step-by-step solution
Using VSEPR theory to analyze molecular geometry: For CH₄ and SiCl₄ , both central atoms ( C and Si ) belong to Group 14 and have 4 valence electrons, forming 4 single bonds with no remaining electrons for lone pairs. The steric number is 4 in both cases, resulting in tetrahedral geometry. Comparing the options: A) Incorrect: both have zero lone pairs B) Incorrect: geometries are identical, not different C) Correct: both exhibit tetrahedral geometry with no lone pairs D) Incorrect: geometries are identical, not dif
