Different possible thermal decomposition pathwasy for peroxyesters are shown below. Match each pathway from List-I with an appropriate structure from List-II and select the correct answer using the code given below the lists

Answer

A, B, C, D

Explanation

`Ator,Btos,Ctoq,Dtop`
Four pathways for reactions are given.
.
Note that first homolytic fission is expected to give `R-overset(O)overset(||)(C)-O^(**)`
`+R'O^(**)`. This is usually unstable (remember kolbe's electrolyses)
and decomposes to `R^(**)+CO_(2)`. But `ph-overset(O)overset(||)(C)-O^(**)` is stable, since it is a difficult bond to break. hence in (p) and (r), which have `Ph- CH_(2)-overset(O)overset(||)(C)-O-O-R` groups, `Ph-CH_(2)^(**)`. will be formed (`because`benzyl radical is stable) so (A) or (B) are possible
pathways for them. for `Ph-overset(O)overset(||)(C)-O-O-R` (q and s), (C) and (D) pathways will be more likely.
`therefore1:` A or B
3: C or D
2: A or B
4: C or D
Now consider `R'O^(**)`. if it is `CH_(3)O^(**)`, it cannot splite.
But
Can occurr. Hence carbonyl compound will be formed with r and s, but not with p and q.
`therefore1`: A or D 3: B or C
2: A or D 4: B or C
