Erythro and threo isomers

What are the erythro and threo isomers? How they are linked with enantiomers and meso compound? Here we will see various examples for identifying these isomers and we will discuss how erytho isomer can act as meso strucure.

Glad to hear that. Thanks for watching.

Excellent sir thank you

[@harshitarora2005]

Thanks a lot ...very helpful

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.

Thankyou sir

[@sanidhyasharma2202]

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

[@pwlakshyastudent7966]

When two similiar groups are in opposite side it is known as Can you please tell me

[@ChemistrybyUKumaraSwamy]

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??

[@skotteeswaran5248]

Bro send this ppt

[@akashkumarsahu9888]

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