Write the equation of chemical reaction and name of reaction obtained fromfollowing compounds $$(A)$$ and $$(B)$$ from $$CH_{3}CHO$$? (A) $$But-2-enal$$ (B) $$Chloroform$$

Solution

The chemical reactions are $$ aldol condensation$$ and $$haloform$$ reactions.
During aldol condensation, $$acetaldehdye$$ is converted into $$but-2-enal$$.
During haloform reaction, $$acetaldehdye$$ is converted into $$chloroform$$.
