Covalent and Dative Covalent Bonding

[@hondicibonga1254]

Thank you so much . You have helped me a lot .

[@shraddhasheth2023]

Do we need to know for the current AQA spec how sigma/pi bonds work? And in more complicated questions if both compounds have a spare pair of electrons how do we know which compound donates their pair and which one receives it?

[@paolariemer3536]

Thank you, this was very helpful!

[@caramianjoku4401]

Life saving 😭😭

[@luckybhai5472]

can u please add video of gaseous state

[@waqaswaqar3176]

can we have four covalent bonds between corbon atoms

[@hanzhang1133]

Waqas Waqar yes such as CH4

[@ramindurrani1295]

Carbon always form 4 bonds

[@MJ177brrr]

Does carbon monoxide have 4 bonds

[@jasminebrook5692]

Do you need to know sigma and pi bonds for AQA? Thanks

[@krablordkek]

no you don't

[@Rawr12319]

As in, how can you work out, from the reactants, what the products will be? is there a way? I'm not sure if they're is that's why I asked :) thank you

[@AlleryChemistry]

+Ashleigh Knowles Not particularly, just have to remember the general reactions really. They all follow some kind of pattern e.g. acid + carbonate will produce salt, carbon dioxide and water. Keep practicing. Exam papers and you will see that many of them you will become familiar with the general products.

[@Rawr12319]

+Allery Chemistry thank you I😆

[@irenepereira5145]

could you please add videos of hybridization

[@AlleryChemistry]

Which exam board do you do?

[@irenepereira5145]

Allery Chemistry as level

[@AlleryChemistry]

Which exam board are you studying though?

[@irenepereira5145]

Allery Chemistry as level

[@MissK233]

He means are you doing OCR, AQA or what?

[@tancos6858]

Is there any video we’re he explains polarastion and iso electronic ions ?

[@TehSainty]

Is the double bond in the oxygen a pi bond?

[@coldrockskeep7956]

thank you 😀😄

[@ksi800]

Where do you get the positive charge in NH4+

[@AlleryChemistry]

Ammonia NH3 has no charge. When add H+ ion you get NH4+ as overall charge is now positive

[@TehSainty]

Also do you do private tutoring?

[@h9.k]

p orbital dumbell shape? and a sigma bond??

[@skylawhite3519]

Could anyone please explain why exactly benzene has 12 sigma bonds?

[@arthurmorgan466]

I’m sure you probably do not need the explanation now, but I’ll say anyway. Essentially the structure of a benzene ring isn’t what most think with every other bond on the carbon chain to be a double bond. That is not right, due to p orbitals that aren’t being used because they are all carbon-carbon single bonds, every carbon atom has a p orbital that sits above and below that carbon atom, these overlap with the p orbitals from other carbon atoms, which creates a pi system. So essentially it’s 12 sigma bonds because kekule’s model is incorrect, there are no carbon-carbon double bonds.

i love you

[@modupeolofinsawe5997]

thank you

[@Rawr12319]

Please could you do a video on how to predict products of a reaction? Thank you :)

[@AlleryChemistry]

+Ashleigh Knowles What do you mean predict products of a reaction?

[@PIX-HUGEIFY]

trying to understand Schrodingers equation (I don't think I even spelt his name right). I just don't understand the way he notates his orbitals need help

[@Fikadusifan]

It can't seen properly

[@tancos6858]

Legend !

[@eleanor1863]

But pi bonds have 4 electrons, 1 pair in the sigma bond and 2 electrons in each cloud

[@truth.twistt]

nidheneeeee urgh
