The correct order of reactivity of phenyl Magnesium bromide with the following compound is:
(II)> (III)> (I)
(I)> (III)> (II)
(II)> (I)> (III)
(I)> (II)> (III)
C.
(II)> (I)> (III)
Among aldehyde and a ketone, aldehydes are more electrophilic as in ketones. If charge on carbonyl carbon is decreased by +I effect of both alkyl groups.
Moreover in the tetrahedral intermediate aldehydes have less steric repulsion than ketone and aldehydes increases the--ve charge on oxygen less in comparison to ketmes.
Based on the above the order of reactivity is:
(II) > (I) > (III)
Under basic condition which one suffers elimination the most?
