If heat is supplied to the stillpot too rapidly, the ability to separate two liquids by fractional distillation may be drastical

hram777 [196]

Answer: The boiling points of the two liquids are quickly exceeded

Explanation:

Fractional distillation is a method of separating a mixture of liquids where each has different boiling points.

To therefore obtain individual fractions, temperature rise of the mixture must be gradual, otherwise the boiling points of the two liquids will be quickly exceeded making collection of each fraction impossible.

Draw the mechanism for the addition of methylmagnesium bromide to propanoyl chloride (CH3CH2COCl) to give 2-methyl-2-butanol.

Ghella [55]

Answer:

Reaction mechanism has been given below

Explanation:

Propanoyl chloride contains an electrophilic carbonyl center to give nucleophilic acyl substitution reaction by removing Cl group with a strong nucleophile like methylmagnesium bromide.
Two equivalent of methyl magnesium bromide react with cabonyl center followed by protonation of negatively charged oxygen atom gives 2-methyl-2-butanol.
In the first step, nucleophilic acyl substituion occurs. In the second step, nucleophilic addition occurs. In the third step, protonation occurs.
Reaction mechanism has been shown below.
