Erythro and threo isomers

[@jesuslove2127]

Excellent sir thank you

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.

Sir in the 1st structure of the class aren't there 2 chiral carbons I.e 2 and 3.....plz tell..

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
