Why does bromine react slowly as compared to bromine vapour?

1 answer:

5 0

Q.1 why liquid br2 reacts slowly as compared to vapours of bromine? Think about collision theory. Gas molecules possess more kinetic energy than molecules as a liquid. Gases thus have a larger frequency of collisions and, additionally, are more likely to possess sufficient energy to overcome repulsive forces, (\(i.e. E_a\)). These factors contribute to a greater likelyhood of a successful collision that results in chemical reaction.

Answer:

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. The difference in mass between the reactants and products is manifested as either the release or the absorption of energy.

Explanation: Read this and you might be able to figure it out for yourself ☺️☺️☺️

Draw structures from the following names, and determine which compounds are optically active:(c) 1,2-dibromo-2-methylbutane

dolphi86 [110]

The given compound 1,2-dibromo-2-methylbutane is an optically active compound .

Because this compound does not have plane of symmetry (POS) and center of symmetry (COS) i.e. does not have di-symmetry . And also forms non superimposable mirror image . the compound is optically active .

It has chiral center.

Here , the chiral carbon is attached to the 4 distinct groups such as : methyl , ethyl , bromine , bromomethane .

<h3>What is di-symmetry?</h3>

Di-symmetry is that which have no center of symmetry and plane of symmetry and alternate axis of symmetry .

<h3>Chiral center :</h3>

Have Sp3 hybridized center (4sigma bond ) .

4 distinct group is attached to the chiral atom. form non -superimposable mirror image .

<h3>What is optical isomerism ?</h3>

Same molecular formula and same structural formula . also have same physical and chemical properties .

They differ in their behavior towards plane polarized light (ppl) .
