Correct order of reactivity of following compounds towards Grignard reagent ?
Correct order of reactivity of following compounds towards Grignard reagent ?
A.
I > II > III
B.
II > I > III
C.
II > III > I
D.
I > III > II
Answer :
II > I > III
Solution :
\[-C{{H}_{3}}\] group give $$+M$$ and $$+I$$ but $$+M$$ work only at ortho and para position. Reactivity \[\propto \] positive charge on carbonyl carbon so that's why reactivity II > I > III.
