An alkene give two moles of HCHO, one mole of CO_(2) and one mole of CH_(3)-underset(O)underset(||)(C )-CHO on ozonolysis. What is its structure ?

Answer»

`CH_(2)=CH-UNDERSET(CH_(3))underset(||)(CH)-CH=CH_(2)`
`CH_(2)=C=CH-underset(CH_(2))underset(||)(C )-CH_(3)`
`CH_(2)-underset(CH_(3))underset(|)(C)=CH-CH=CH_(2)`
`CH_(2)=C=CH-underset(CH_(3))underset(|)(CH)-CH=CH_(2)`

Solution :`CH_(2)=C=CH-underset(CH_(2))underset(||)(C )-CH_(3) overset(O_(3)//Zn+H_(2)O) RARR 2HCHO+CO_(2)+CH_(3)-CO-CHO`
