How many different organic products are formed on exhaustive ozonolysis of the diene shown? Ozonolysis is carried out with $O X_{3}$ followed by $Zn$ / $H X_{2} O$ (reductive work-up), cleaving every C=C; count distinct organic molecules formed.

A $2$
B $3$
C $4$
D $5$

Answer: B

The compound shown is penta-1,3-diene. Cleavage of the C1=C2 bond gives methanal, cleavage of C3=C4 gives ethanal, and the central fragment C2-C3 becomes ethanedial (glyoxal),

OHC - CHO

. That is 3 different products.
