Answer:
16.06 L was the initial volume of the balloon.
Explanation:
Initial moles of freon in ballon =
Initial volume of freon gas in ballon =
Moles of freon gas added in the balloon = n = 3.50 mole
Final moles of freon in ballon =
Final volume of freon gas in ballon =
Using Avogadro's law:
( at constant pressure and temperature)
16.06 L was the initial volume of the balloon.
Answer:
Explanation:
The reaction between dimethyl malonate which is an active methylene group with an (∝, β-unsaturated carbonyl compound) i.e methyl vinyl ketone is known as a Micheal Addition reaction. The reaction mechanism starts with the base attack on the β-carbon to remove the acidic ∝-hydrogens and form a carbanion. The carbanion formed(enolate ion) attacks the methyl vinyl ketone(i.e. a nucleophilic attack at the β-carbon) to give a Micheal addition product, this is followed by the protonation to give the neutral product.
