Allery Chemistry Most of the British pennies are either a copper alloy or a ferrous metal plated with copper. I had some old coins and someone told me adding ethanoic acid and sodium chloride, both common household items, would remove the rust, cooper oxide from the old coins....and It worked!!!!!! I had no idea how please explain. Thank you
at around 7 minutes, you said the oxygen has a positive charge because it has too many bonds but oxygen has 6 electrons in its outer shell and is only forming three bonds so how is that too many?
Thank you so much for this video , very helpful ..question : sodium hydroxide is diluted in water ,then , what happens exactly between the two mechanisms , and the final products ? Thank you , Fred / France
Hello, in the reaction with water, in the last step, what happens to the br-, as youve added H+, but I was just wondering if the br- is still present? Thank you :)
MasterPrestige#fifa No problem. The videos are for all exam boards. Just double check your spec to make sure content is relevant. It's difficult to pin certain videos to certain boards due to new specifications due to come in next academic year. Please follow me on twitter to get pre release info on videos @allerytutors.

What would be the reaction if a Halogenoalkane reacts with aqueous silver nitrate in ethanol? it is in the specification for Edexcel and I have no idea how the reaction would look like
HBr will not form in reaction with H2o becous water is a polar protic solvent due to its protic nature it will surround the Br- 1st , due to which all br- will be surrounded by h2o and no hbr will form ,, SIR PLEASE REPLY IF I AM RIGHT??
One of the best teachers I've ever seen. ^.^
Cheers! Please share this channel with your friends. The more people that use it the better! 😀
thank you for including the reaction with water
👍 very detailed explanation
This might be a little personal,
but do you have a PhD in chemistry?
You teach better than my teacher who DOES have a PhD in chemistry!
thank you
No I don't have a PhD. Just a passion for chemistry and education. You certainly don't need a PhD for that. :-)
Allery Chemistry You're quite correct. on that note..I have a question about chemistry unrelated the the exam this afternoon.
Yes go for it.

@@unknownhuman3659 lmao
You're such a great teacher! your videos are great!
i dont understand why the bromine has a 1- charge, shouldnt it be 2- as it has gained 2 electrons?
at around 7 minutes, you said the oxygen has a positive charge because it has too many bonds but oxygen has 6 electrons in its outer shell and is only forming three bonds so how is that too many?
In h20 there are 2 lone pair of electron on oxygen, you have shown only one lone pair in the mechanism, Where did the other one went?
Don’t need to show both
This is easy to understand and hopefully i'll get this correct in my exam!!!
you look like Seth Rogen and ur an amazing teacher.its a WIN WIN.

your videos are so helpful, thank you so much
Glad you like them!

I am in love with you
With the water, do you need another water molecule so that the hydrogen ion gets removed from the oxygen if that makes sense, like with the ammonia
Thanks for your vids, I'm studying edexcel AS, is your vids for edexcel? Or aqa or both, thanks.

Thumbs Up 👍👍👍👍
+Fahad Imtiaz Given you one too!
very helpful, thank you
Thanks bigman. Legend
Thank you very much, your video did help a lot for me :)))))))))
Jamba Jamba Thanks! Please share the video and follow me on twitter @allerytutors for pre-release information on videos and future project news.

Same here

why is ethane unstable if OH is attached to the carbocation?? I didnt get that point sir!
7:59 you mean hydrobromic acid since it is aq, hydrogen bromide is for gas
why does water only has one lone pair? love ur vids btw
It has 2. Only show 1 in mechanisms as only one gets involved in the reaction.
Why are the electrons on the water being spread over 2 many places?
God bless you, thank you so much!!!
What's the condition for nucleophilic substitution with OH-?
Heat under reflux with a solution of sodium or potassium hydroxide (source of OH-) in a solution of 50/50 ethanol and water
he can teach but the board is very clustered
Thanks. Will take this on board on my next videos.
Allery Chemistry haha take this on “board”
