Glad to hear that. Thanks for watching.

Thank you sir for making it clear... I have an question ... At 7:50 , you said that the 2,3 -Dichlorobutane is optically active...but this compound is meso compound... has plane of symmetry .. two chiral centre.. A meso compound can not be optically active ...Sir , tell this please.

[@egpat]

2,3-Dichlorobutane has two chiral centers with one plane of symmetry. Therefore it gives 3 optical isomers. One is dextro, another is levo, both of these are optically active. Third one is meso which is optically inactive.

Thanks sir

Sir..in..2 bromo 3 chloro butane we use thik line with Cl and Br... instead of dotted lines is it possible

[@simrinahmed5436]

no, the second carbon is connected to 2 hydrogens.

Achha explain kiya lekin hindi me kiya hota to aur bhi achha lagta. Thank you Sir

[@AtulKumar-tn8or]

What is this D and L, is it an abbreviation of dextro and levo respectively??

[@akashkumarsahu9888]

How 2,3 - Dichloro butane is optically active? It should be inactive as it has plane of symmetry
