CH - CH = O + CH - C- CH □(→┴NaOH )
(a) 5 (b) 2
(c) 3 (d) 1

Answer 1

Answer:

(d)1 ✔✔

hope its help uh mate

Answer 2

The number of cross aldol products formed  (without counting  stereoisomers)  are 1

• Aldol condensation: The process of reacting aldehydes or ketones in presence of dil. NaOH to β hydroxy aldehyde or β hydroxy ketone known as Aldol.
• Aldol condensation produces 4 products.
• But if one of reacting species doesn;t have α Hydrogen atom , then only 2 products are formed, as in this case.
• It behaves just as a anion acceptor.
• Also , it is said to not count on stereoisomers.
• Therefore we have only 1 product left.
