1) option c (4)
2)
Reaction is aldol condensation
3) electrophilic aromatic substitution ability of the ring
increase when there is an electron donating group present in the
ring. When electron withdrawing group present, the ability
decrease.
So the order is as follows.... C>E>A>B>D.
Hence the answer is option b
4)
Grignard reaction of lactone.
5)
PCC oxidation. Primary alcohol will be oxidised to aldehyde, secondary alcohol will be oxidised to ketone, tertiary alcohol will be unaffected
