MCQ
The angle between $s{p^2}$orbitals in ethylene is......$^o$
- A${90}$
- ✓${120}$
- C${180}$
- D${109.5}$
✓
Answer
Correct option: B.
${120}$
b
The three equivalent $sp ^2$ orbitals will arrange themselves in a trigonal planar configuration. That is to say, the carbon nucleus will be at the center of an equilateral triangle, and the three $sp ^2$ orbitals will point to the corners of that triangle. The ideal angle between $sp ^2$ orbitals is therefore $120^{\circ}$.
