3-Methylpentane on monochlorination gives four possible products. The reaction follows free radical mechanism.The relative reactivities for replacement of -H are `3^(ul@):2^(ul@):1^(ul@)` =6:4:1.
Relative amounts of A,B,C and D formed are
A. 6/31,16/31,6/31,3/31
B. 16/31,6/31,6/31,3/31
C. 6/31,16/31,3/31,6/31
D. 6/31,3/31,6/31,16/31
