One mole of a symmetrical alkene on ozonolysis gives two moles of an aldehyde having molecular mass of 44u . The alkene is :

A

2- butene

B

ethene

C

propene

D

1- butene

Text Solution

Verified by Experts

The correct Answer is:
A
`underset("But -2- ene")(H_(3)-HC)=CH-CH_(3)underset(Zn,H_(2)O)overset(O_(3)//C Cl_(4))tounderset(("Molar mass -44u"))underset("Acetaldehyde")(2H_(3)C-overset(O)overset(||)(C)-H)`
