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 ?

Options

A. `CH_(2)=CH-underset(CH_(3))underset(||)(CH)-CH=CH_(2)`
B. `CH_(2)=C=CH-underset(CH_(2))underset(||)(C )-CH_(3)`
C. `CH_(2)-underset(CH_(3))underset(|)(C)=CH-CH=CH_(2)`
D. `CH_(2)=C=CH-underset(CH_(3))underset(|)(CH)-CH=CH_(2)`

Answer

B

Explanation

`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`
