The correct options are
A Reaction can be catalysed in acidic or basic medium
B A new C-C bond is always formed
C CH3CHO and
D3CCHO reacts at same rate if all other conditions are similar
D CH3−CH=CH−O||C−H
for aldol condensation reaction
α hydrogen elimination does not occur
Condition of aldol condensation :
i) The reaction can be catalysed in baric medium.
ii) A new c−c bond is always formed.
iii) CH3CHO and D3CCHO reacts at same rate if all other condition are similar.
iv) CH3−CH=CH−O−H , B - hydroxyaldehyde is produced. For aldol condensation reaction of hydrogen elimination does not take place.
