Per NCERT §4.6.1, BCl₃ has its boron sp² hybridised. What is the molecular geometry + bond angle?
ATetrahedral; 109.5°
BLinear; 180°
CTrigonal planar; Cl-B-Cl angle 120°
DPyramidal; 107°
Answer & Solution
Correct answer: C. Trigonal planar; Cl-B-Cl angle 120°
Per NCERT §4.6.1(II), sp² → trigonal planar, 120° (e.g. BCl₃). 33% s + 67% p in each sp² hybrid.
