Chiral vs Achiral Molecules - Chirality Carbon Centers, Stereoisomers, Enantiomers, & Meso Compounds

This organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. It shows you how to identify the chirality centers or carbon atoms with 4 different groups as well as determining the number of stereoisomers using the formula 2^n where n is the number of stereocenters or asymmetric carbon atoms. This video also helps you to identify a pair of meso compounds which are identical to each other and a possess an internal plane of symmetry. It also discusses how to find a pair of enantiomers which are non-superimposable mirror images of each other such as your left hand and your right hand. Enantiomers lack an internal plane of symmetry.

    Confused a bit at 8:17, you say that it cannot be divided as a mirror image but the way you drew it can actually be divided. If you lay down the molecule and cut it along it's middle axis like a sandwich you could split it. I think once you add in the H going away from or into the paper then you can on longer divide it in half. I think the OH group in that drawing should be coming out or going into the page to account for the implied hydrogen.
