Why are plastic containers preferred to glass containers for storing chemicals in the laboratory?
Nookie1986 [14]

Which pair of reactants will undergo aldol condensation to produce methylvinyl ketone?
xenn [34]

When formaldehyde and acetone then react with each other( aldol condensation) then it will be formed <u> methyl vinyl ketone.</u>

<u />

In organic chemistry, an aldol condensation would be a condensation reaction in which an enol and enolate ion combines with a carbonyl chemical to produce a -hydroxy aldehyde or -hydroxy ketone, that is then dehydrated to produce a conjugated enone.

In aldol condensation, when  formaldehyde and acetone then react with each other then it will be formed <u> </u><u>methyl vinyl ketone.</u>

It can be written as

CH_{2} O + CH_{3} COCH_{3} → HOCH_{2} -CH_{2} -CO-CH_{3}

When it will be heated then it gives methyl vinyl ketones.

HOCH_{2} -CH_{2} -CO-CH_{3} → CH_{2} =CH-CO-CH_{3}

So, the pair of reactants will be formaldehyde and acetone
