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) .

<u>Answer:</u> The spacecraft traveled 345 km during the given time.
<u>Explanation:</u>
To calculate the distance of spacecraft, we use the equation:
We are given:
Velocity = 2.3 km/sec
Time = 2.5 mins = 150 sec (Conversion factor: 1 min = 60 sec)
Putting values in above equation, we get:
Hence, the spacecraft traveled 345 km during the given time.
