aleksley [76]

Answer:

Explanation:

A sigma bond is formed when a hybrid orbital sp overlaps with another hybrid orbital or with s- or p- orbital

Ethylene has a structural formula of H - C≡ C- H

At the ground state; we have :

C | ⇅ | |↑ | ↑

2s 2p

At the excited state, we have:

C | ↑ | |↑ | ↑ | ↑

the hybrid orbital

C = | ↑ | ↑ |
