Sir
Kindly refer to these questions of set B
2.11 option b
In this option instead of = (equal to sign) , there should be >=(greater than or equal to sign) Equality is one special case
IzI + IwI >= Iz+wI ….1
IzI + IwI >= Iz-wI …2
Now adding 1 and 2
3.5 option d
I think answer is c
3.10 option c
I think answer is b
4.1 option b
suggested answer c
4.8 option c
suggested answer a because in light free radical subsitution occurs most rapidly at 1(degree) carbon
4.10 option d
suggested answer b because its pH is maximum
4.14 option ab
