But I'm so dumb. .. I shudda known this coz i had just completed organic chem A level few weeks backYeah That was completely out of the blue.

I honestly don't know, but it seems like the only reaction to fit. Its maybe got to do with the yield.Were we supposed to specify under standard conditions/states when they asked for enthalpy change of reaction? Because they didn't say STANDARD enthalpy change of reaction
And what did you guys say for electronegativity definition?
Note: why would they expect us to say propanoic acid for reaction 2 (to form X) when you're just going to hydrolyse it to form propanoic acid again?
It was only for 2 marks. Hoping that the gt is low, it should not make much of a difference.But I'm so dumb. .. I shudda known this coz i had just completed organic chem A level few weeks back
Yea In sha AllahIt was only for 2 marks. Hoping that the gt is low, it should not make much of a difference.
Find the Mr of the compound, (NH2)2CO ==> 2(14+2)+12+16=60How many H atoms are present in 25.6g of urea, (NH2)2CO? How to solve such questions?
The impurity is sulfur.Guys, I just took the paper yesterday, what exactly is the contaminant in carbonaceous fuels again?
Also, what reagent to reduce carboxylic acid to primary alcohol? NaBH4 or H2/Ni can? Because I heard it's LiAlH4..
And the reaction between Al2O3 with HCl can form Al2Cl6 or not ya? Some said it was AlCl3 only..
I wonder if acyl chloride is also a possible reagent for making the amide?
Sorry for retarded questions.. First post.. xD
Naturally occurring copper is composed of 63Cu with an atomic mass of 62.94 amu and 65Cu with an atomic mass of 64.93 amu. Find the abundance of 63Cu isotope.
Thankyou sooooo much! This is amazing!
Wait till 21st january. (My bday)anyone having question paper for chemistry paper 2 oct 2015 plz upload it
