@Martin-マーチン Weird, I guess And SE Lisk made it for his questions, I wouldn't mind nuking it personally.

@ArtFowler I'm pretty sure you didn't o.O

Hi, can I ask a question? Suppose we have a $CH_3CH_3$ molecule and we make it an ethyl cation $CH_3CH_2^+$ then will a p-orbital of the second carbon un-hybridize by itself because now it's an empty orbital?

Actually I was studying about Hyperconjugation effect, and I saw this diagram drawn in my book. I was confused how could an $sp^3$ hybridized orbital unhybridize by itself when an electron was removed from it. Please share your valuable suggestions. :-)

MERRY CHRISTMAS TO EVERYONE $\huge{⛄☃🎅🎄🎁}$

@user8718165 It doesn't "unhybridise", hybridisation is not a physically observable process, it is a mathematical description which follows from the geometry of the molecule.

A more accurate way of phrasing it would be that the geometry of the molecule does change. This would indeed correspond to a different hybridisation.

@orthocresol Hello :-)

@orthocresol Thank you so much for clearing my doubt. :-)
