@TheLonghairraven No, not necessarily, watch the video again, in the later part you'll see that the cyclopentane has 2 chiral atoms, but the molecule as a WHOLE is superimposable hence not a Chiral MOLECULE. :) So it depends, you must analyse it correctly.
Isn’t the 1,3-Diflourocyclopentan achiral if the fluorine groups are pointing in the same direction but chiral if one of them is pointing out of the plane and the other into the plane?
Actually how do you name the molecule at the beginning of the video? How do you name the hydroxide? I know that fluorine becomes fluoro, chlorine becomes chloro. What does hoydroxide become? Hydroxo?
Sal, great work with the organic chemistry, i really think your filling a conceptual niche thats lacking with this subject on youtube, if you would not mind can you thoroughly explain stereo-chemistry, and acid/base chemistry as it relates to organic chemistry and reactivity,
P.S. Can you organize the organic chemistry into a playlist please? Thanks alot for these videos Sal!

so does having a chiral carbon means its automatically a chiral molecule as well??

DR. Khan!!! Thank you I wish i could repay you for doing what my Ochem professor couldn't...teach.

good job on the vid, dr. khan, but I have a question- what role does the fluorine play in determining chirality at 7:20

If you have individual chiral centres in a molecule, would the whole molecule be chiral?

One problem with the difluoro cyclopntane compond: it has Z and E izomers and can be Chiral
