Anyone please help me with V and W ? Shouldn't Oxygen be replace with O-H bond ? View attachment 62717 View attachment 62718
It's on 25th October... It's Paper 2 tomorrowAnyone doing Chemistry Practical 34 on the 17th October??? Pls help if possible✌
Thanks for thatIn this question test 1 is for the basic identification of whether the substance is an amide or amine. Since M does not react with the acid, this means that the substance must contain an amide group (it is neutral). Since the only other group we know containing nitrogen is amine, and it would react with the acid, we can safely assume the other substances all contain an amine group. In terms of test 5, it can test for either a hydroxy group, an acid, nucleophilic substitution or hydrolysis. remember that either an acid or an alkali can be used in hydrolysis. For the reaction with M, you should be able to see that the amide has hydrolysed into phenylamine and sodium propanoate.
EDIT: My bad, this is for the second question
bro please help.... i have posted the question above this post..........Alright, Bishnu, typing my response to you.
(0.5-0)/50 = 0.01 x 100 = 1%bro please help.... i have posted the question above this post..........
Is your P3 exam tomorrow?bro please help.... i have posted the question above this post..........
I'm really late, but I'll still explain it seeing that the chem p5 is tomorrow. I think the enthalpy of reaction would become more exothermic as Ecell increases, since the oxidation and reduction of the two species occurs more readily in those cases.View attachment 62733 From 52/M/J/16 . Anyone please explain 1) a)?
The answer is A....
You may have thought that there would only be 3 isomers instead of 4 isomers, however there is an extra twist to this question: there are two isomers for the variation in which 2 chloro groups are next to each other. The chloro groups may bond to neighbouring carbon atoms that have a double bond between them, or a single bond. In addition to the 2 other isomers with 1 carbon in between and 2 carbons in between, you will get 4 isomers instead of 3.
As Daniel Jeng said,
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
