The Amount of Valuable information in these videos.... And the fact that you are uploading them for free for us students!! That's such a huge act of Kindness. You are helping so many people get good grades, and thus also better university placements...God Bless you bro.
Hi, could anyone please answer my question: at 4:08, he said "as the nitrogen has too many bonds, it now have a positive charge" and why would it have a positive charge? if it has more bond, does it not mean it gets an extra electron to be paired and therefore a negative charge? sorry if this doesn't make sense, but I'm a bit confused. thanks
Usually, when a nitrogen atom forms an extra, 4th bond, it uses its lone pair of electrons to form a co-ordinate, dative covalent bond to the other atom it is bonding to. Now, once this co-ordinate bond forms, one of the electrons in the bond can now be thought of as 'belonging' to the new atom the nitrogen has bonded to, and one as belonging to the nitrogen. From this, the nitrogen atom would end up with a positive charge as it can be considered as having 'lost' an electron. We can get deeper into this when thinking about formal charges and lewis structures, however hopefully that helps :)
WHY DID I FIND THIS CHANNEL ONLY 2 WEEKS BEFORE THE EXAM this is the holy grail of a level chemistry
Good luck with your exams!
