Question

explain optical isomerism in 2 chlorobutane​

Answer 1

Answer:

Answer: 2-chlorobutane is an optically active molecule. the carbon numbered as 2 in the molecule is chiral as it has different substituents [-c2h5, ch3, H, Cl] attached to it. thus it rotates plane polarised light in different directions giving rise to two enantiomers [R, S] of the compound.

plz mark me as brainliest plz

Answer 2

Answer:

1. 2-chlorobutane is an optically active molecule having molecular formula C4H9Cl.

2. A compound to be said as optically active is only if it has to have an asymmetric chiral carbon centre and a carbon is said to be chiral if the have different substituents attached.

3. In 2-chlorobutane the carbon numbered as 2 in the molecule is chiral as it has different substituents [-C2H5, CH3, H, Cl] attached to it.

4. It gives rise to enantiomers by rotating the plane of polarized light in different directions (R) and (S) of the compound
