Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Concept introduction:

In aldol reaction, joining of two reactants takes place.

The only acidic C-H atom in but-2-enal is present on C4 carbon atom, which is attached to the carbonyl carbon of the 3-phenylpropenal, resulting in the formation of an aldol product.

In heterolysis, water is removed, and alkene is formed.
