Two steps in a synthesis of the analgesic ibuprofen include a carbonyl condensation reaction, followed by an alkylation reaction
Tresset [83]
Ibuprofen is synthesized by reacting ethyl 2-(4-isobutylphenyl)acetate with base, the base abstracts the acidic proton and enolate is formed which on reaction with diethyl carbonate generates diethyl 2-(4-isobutylphenyl)malonate (A). diethyl 2-(4-isobutylphenyl)malonate on treatment with Base again looses the acidic proton and forms enolate. The enolate with treatment with Methyl Iodide yields diethyl 2-(4-isobutylphenyl)-2-methylmalonate (B). diethyl 2-(4-isobutylphenyl)-2-methylmalonate on hydrolysis give Ibuprofen.

How many moles of PCl5 can be produced from 24.0 g of P4
posledela

Hey there!

Given the reaction:

P4 + 10 Cl2  ------------------ 4 PCl5

Molar mass P4 = 124 g/mol

Number of moles P4:

n = mass of solute / molar mass

n = 24.0 / 124

n = 0.1935  moles of P4

Therefore:

1 mole P4 --------------- 4 moles PCl5

0.1935 moles P4 ------- moles PCl5

moles PCl5 = 0.1935 * 4

= 0.774 moles of PCl5

Hope that helps!
