Question

The geometry around carbon in CH2=CH2 (ethene) is:

RankGuru · Accepted Answer

1. **Structure**: $H_2C=CH_2$. Each Carbon atom forms $3$ $\sigma$ bonds (2 with H, 1 with C) and $1$ $\pi$ bond.
2. **Steric Number**: Since $\pi$ bonds do not contribute to geometry, the steric number is $3$ (3 $\sigma$ bonds).
3. **Hybridisation**: Carbon is **$sp^2$** hybridised.
4. **Geometry**: The three $sp^2$ hybrid orbitals are directed toward the corners of an equilateral triangle to minimize repulsion.
5. **Bond Angle**: This results in a **trigonal planar** arrangement with bond angles of approximately **$120^\circ$**.
