Only symmetrical alkenes upon ozonolysis give one product.

Among the given alkenes, only $2 - b u t e n e$ is a symmetrical alkene and undergoes ozonolysis in the following manner.

$C H_{3} C H = C H C H_{3} O_{3} / H_{2} O_{2} - ---- \to 2 C H_{3} C H O A c e t a l d e h y d e (a l d e h y d e)$ .
