Které typy vazeb spoluvytvářejí trojnou vazbu?
Správná odpověď je: A
Vazba sigma je název pro chemickou vazbu, která vzniká na nejkratší možné spojnici jader atomů. Vazba pí je taková, která vzniká na druhé nejkratší spojnici, tedy kolem vazby sigma. Trojná vazba obsahuje dvě vazby pí a jednu sigma vazbu. Dvojná vazba pak obsahuje jednu vazbu pí a jednu sigma. Jednoduchou chemickou vazbu tvoří pouze vazba sigma.
