Ethanal has one methyl group attached with Carbonyl group, so it gives a positive iodoform test but propanal does not give this test. ... Cross aldol condensation - In aldol condensation, if the reactants are two different aldehyde or ketone, then it is called cross-aldol … WebAn aldol reaction that starts with two different carbonyl compounds is called a crossed aldol reaction. Unless specific conditions are involved, a crossed aldol reaction can lead to a mixture of products from various pairings of the carbonyl reactants, as the following example illustrates with ethanal and propanal. dry erase board paint colors WebAldol condensations between different carbonyl reactants are called crossed or mixed reactions, and under certain conditions such crossed aldol condensations can be effective. Example 3: Mixed Aldol Reaction. The success of these mixed aldol reactions is due to two factors. First, aldehydes are more reactive acceptor electrophiles than ketones ...
