Question

Сколько п-связей содержит молекула пропина

Answer 1

CH₃-CH₂-C≡С-CH₃ (пропИН) = 2π связи

Answer 2

Molecular Structure of Propyne

The molecule propyne, also known as methylacetylene, has a chemical formula of C3H4. It is an alkyne with a triple bond between two carbon atoms.

Number of Sigma (σ) Bonds: The molecule propyne contains sigma (σ) bonds, which are the single covalent bonds between atoms. In the case of propyne, it contains sigma bonds between the carbon atoms and hydrogen atoms.

Number of Pi (π) Bonds: Propyne also contains pi (π) bonds, which are formed by the overlap of p-orbitals. In the case of propyne, it contains a triple bond, which consists of one sigma bond and two pi bonds.

Therefore, the molecule propyne contains 2 sigma (σ) bonds and 2 pi (π) bonds.
