Answer:
This is an example of (substitution nucleophilic bimolecular) reaction
Explanation:
Conversion of t-butyl alcohol to t-butyl bromide proceeds through (substitution nucleophilic bimolecular)mechanism.
In the first step, -OH group in t-butyl alcohol gets protonated.
In the second step, stable tertiary carbocation (t-butyl cation) is produced by removal of .
In the third step, bromide ion attacks to t-butyl cation and produces t-butyl bromide.
Removal of from n-butyl alcohol will produce an unstable primary carbocation (n-butyl cation). Hence, to produce this unstable carboction, large amount of activation energy is required. Therefore, n-butyl alcohol gives much slower reaction with HBr.
Reaction mechanism has been shown below.
Assuming it's a perfect gas, we have PV=nRT hence V and T are proportional. T increased by 2600/650=4 times hence the volume will be 4 times bigger, which is 200L
By looking at it and if it is making a single movement it is moving.
The question is incomplete, the complete question is;
Determine whether each melting point observation corresponds to a pure sample of a single compound or to an impure sample with multiple compounds.
Experimental melting point is BELOW literature value
Experimental melting point is CLOSE to literature value
WIDE melting point range
NARROW melting point range
Answer:
narrow melting point-pure sample of a single compound
experimental melting point is close to literature value-pure sample of a single compound
wide melting point range-impure sample of multiple compounds
experimental melting point is below literature value-impure sample of multiple compounds
Explanation:
The experimental melting point of a pure single compound is sharp and extremely close to the melting point of the substance as recorded in the literature. Usually, a pure substance melts within a narrow range of temperatures.
Impure samples of multiple compounds melt over a range of temperatures. Also if the experimental melting point is well below the record in literature, then the sample is contaminated by other compounds.
