As per your syllabus, in sp³ hybridisation (e.g. CH₄), each hybrid has 25% s + 75% p character. What is the H-C-H angle and shape?
A104.5°; bent
B109.5°; tetrahedral
C90°; square planar
D120°; trigonal planar
Answer & Solution
Correct answer: B. 109.5°; tetrahedral
As per your syllabus, CH₄ sp³ → tetrahedral, 109.5°.
NH₃ also sp³ but bond angle 107° (1 lp); H₂O 104.5° (2 lp).
