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

In which of the following substances does sharing of electrons between two atoms occur?
sammy [17]

<u><em>Answer:</em></u>

  • PO4∧-3

<u><em>Explanation:</em></u>

Phosphate ion has covalent bond. As we known , covalent bond is formed by sharing of electrons between two atoms. As in this case, P form three single covalent bond with three oxygen atoms and one double covalent bond with one oxygen . The formal charges is -3.

While He is present in mono atomic form

NaI have ionic bond which is formed by donating electrons from one atom and other accept.

Ag is present independently with no other atom.
