Match the procedural step to its purpose by dragging each step in the written procedure for the aldol condensation of dibenzyl ketone and benzil in ethanol solution in the presence of potassium hydroxide base, followed by the UV analysis of the product in hexane solution.

The procedural step for the aldol condensation of dibenzyl ketone and benzene in ethanol solution is matched to its procedural step i.e.

TO MINIMIZE THE FLAMMABILITY RISK ASSOCIATED WITH ETHANOL.

Explanation:

Here, the given reaction is an aldol condensation of dibenzyl ketone and benzil present in the ethanol solution also there is presence of potassium hydroxide base which gets followed by the UV analysis in hexane solution followed by the uv analysis.

This reaction has to be matched with the step i.e.

to minimize the flammability risk associated with the ethanol.

The acetophenone is considered to be asymmetrical but there is only alpha hydrogen with carbonyl on one side so it will generate only one type of Enolate nucleophile.

The possible only one aldol product for the given reaction.

away from the curb

explanation:

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
