PHASE TRANSFER CATALYSIS

$()Name$

Date

Carbene $(H_{2}C$:$)$ is a intermediate:

a$.$ Positive

b$.$ Negative

c$.$ Neutral

Phase transfer catalyst helps to:

a$.$ Catalyse the reaction.

b$.$ Transfer ions from inorganic phase to organic phase for reaction.

c$.$ Transfer ions from organic phase to inorganic phase for the reaction.

d$.$ I have no idea!

The purpose of stirring the reaction vigorously is to:

a$.$ Make sure the reaction is proceeding.

b$.$ Make sure the catalyst is able to go in both phases.

c$.$ Shorten the reaction time.

d$.$ Keep the temperature low.

Extraction of the product will be done by:

a$.$ Using methylene chloride to extract the product.

b$.$ Washing the reaction mixture with sodium chloride solution.

c$.$ Using water to wash the reaction mixture.

The product will be the lower layer in the separatory funnel. $T$ F

The whole lab should take about:

a$.2$ hours

b$.3$ hours

c$.4$ hours

d$.$ more than $4$ hours
