c part? Either is correct in recent paper as i saw in a question both were accepted RCOOH and RCOO- as the product of reaction with tollens.This is an old one so dont worry. -

What year is this?Shouldnt it be that the iodine is displaced from by Cl2,and that would give a brown color to the solution?Maybe if all the I is displaced that would lead to Cl2 going in excess and causing solution to turn yellow maybe?Still what year is this from? -

Shouldnt it be H3PO3?Look on the Oxygen atoms on both sides -

I mostly prefer SOCl as it gives more simpler products,the derivative,SO2 and H20 But Iodo and Bromo bug me.I know them but what should we generally use. -

BTW what are the 3 sure ways of making Halogen derivatives from Alkenes Alcohols Lots are given in the book and some have conditions like heat in situ but what method should we use to make the above derivatives,that can be easily memorised -

I think that may have been a typo in the ms,it shouldnt be there -

Look closely. Its the CH2OH group that is oxidised not the carbon youvd highlighted.so it can be oxidised -

Is So3 connected via PD PD forces or Van Der waals?Shouldnt it be PD PD Due to difference in e-vity of S and O?Or is SO3 symmetrical?. Also are large scale uses of halogenoalkanes,naoh and other such compounds included.What are included. Also when HCL is dissolved in water is the bonding... -

A Are you sure its Hot Conc K2Cr2O7 and not KMnO4? -
Chemistry: Post your doubts here!
Well,isnt KMnO4 an oxidising agent?IT IS first and foremost,its the conditions that cause it to break the C=C,but along with that it will oxidise anything it can ,which include the OH and COH groups. It isnt just for breaking the C=C,it oxidises too and that you shouldnt forget.Both k2cr207 and... -

Use Hess's Law and construct a cycle 2C + 3H2 ---> 2CO2 + 3H20 (These are the Del H of formation of CO2 and H20) C2H6 + 3.5O2 ----> 2CO2 + 3H20 ( Del H of Comb of ethane) As you can see both have the same products,hence you can construct a cycle and work out how C2H6 can be formed from 2C and...
