One more qdo we have cyclic hydrocarbons i guess one q had come abt propertiescan somebody give info abt topics related to this..........
Depends on the q, here its vitamin C. Usually all vitamins contain -OH groups. Only for the structural formula you need to specify -OH and not the molecular formula. For Q.7 b)iii) There are 'n' number of types of chlorination. This depends on how much chlorine you use and which hydrocarbon you use.When chlorination occurs it replaces one hydrogen atom from the hydrocarbon and forms HClE.g. Chlorination of methane:: H H | | H- C - H + Cl2 ------> H- C - Cl + HCl | | H HCH4 + Cl2 ----> CH3Cl + HClProduct:: Chloromethane (methyl chloride) Similarly, CH3Cl + Cl2 ----> CH2Cl2 + HClProduct:: Dichloro methane (methylene chloride)CH2Cl2 + Cl2 ----> CHCl3 + HClProduct:: Trichloro methane (Chloroform)CH3Cl3 + Cl2 ----> CCl4 + HClProduct:: Tetrachloro methane (Carbon tetrachloride/Pylene) I think you only need to know the names in bold. For your question, choose any of the following reaction BUT using butane and chlorineEg. C4H11Cl + Cl2 ----> C4H10Cl + HClOR to be safe give acc. to the quesCH3-CH2-CH2-CH2-Cl + Cl2 ----> CH3-CH2-CH2-CHCL2 + HCl H H H H H H H Cl | | | | | | | |H-C-C-C-C-Cl + Cl-Cl----> H-C- C-C-C-Cl + H-Cl | | | | | | | | H H H H H H H HDon't understand anything.. pls. ask.. Just under the concept of chlorination they may ask any other alkane next time Draw the structures yourself you'll understand better
~VIN1094~, for w08, Q7) b) iii), I do not get it at all. The mark scheme says either 1 or 2-chloropropane is the product of the reaction, and that HCl is not a product.Please explain, many thanks in advance.
I am soryy VIn but the q says thatWrite a diff eqn for a substitutuin reaction between butane and chlorine

I just gave you an example of methane... and how to name ...Got it?
I am sorry VIn but the q says thatWrite a diff eqn for a substitutuin reaction between butane and chlorine
I was looking at the wrong part of the question, oops!Anyway here is the answer to your question:CH3-CH2-CH2-CH3 + Cl2 -> CH3–CH2–CH(Cl)–CH3 + HCl.That's right, isn't it?
Yes it is, but this reaction is given in the question itself! They are asking for different reaction...
~VIN1094~, apparantly that's the trap CIE wanted people to make. In the question, it does say a different equation for a substitution reaction between butane and chlorine, and not an additional chlorination of 1-chlorobutane.So the product formed in my example is 2-chlorobutane as supposed to the 1-chlorobutane in the example.
YES! You are right, I am a fool. Thanks now i get it

r u sure???/
