thats with halogens my friendAlkenes undergo electrophilic addition
thats with halogens my friend
elecrophillic addition is only when Cl2 or Br2 reacts with alkene.......... end of discussionHalogenoalkanes undergo Nucleophilic Substitution

damn.. thnx nbtw, do you know aboutany of the other doubts ive highlighted?In the first question the pH of Al chloride was in the range 1-3
and the reaction was hydrolysis.
good that u posted this the OH is for the acidic solution (catlysed) but the halogen (Br2 or Cl2) is in the aqueos media.... its just above the one u posted
and another thing its not in the syllabus the one ur taking aboutgood that u posted this the OH is for the acidic solution (catlysed) but the halogen (Br2 or Cl2) is in the aqueos media.... its just above the one u posted

Yeah thts right!!ANY addtion reactions of alkenes are electrophilic, dude.
327 is a high temperature for this reaction as it was exothermic so while the reaction takes place it will also generate heat thus its a pretty good temp..........
Lool there is no enthalapy change of formation on an element like H2 but there is definitly and enthalpy change of combustion and u had to use it!One more thing about enthalpy change. How was it 129, + or -. mine was coming 400 something
I asked some candidate( s ) who got 129 kJper mol , but they took also the enthalpy change of combustion of H2( g ) while making the cycle ( Hess's law ). I thought data of enthalpy change of combustion of H2( g ) was a trick! Because there's no enthalpy change from H2 ( g ) to H2 ( g )!
Anyone else got this??
I actually think this IS the right ans...as AlCl3 is nt stable...guys what are your thoughts on this for the aluminium burning in chlorine question i wrote the equation as 2AL(s) + 3Cl2(g) ---> Al2Cl6(g) is the examiner gona allow this?
Man that's was the only reason i wrote it and since everyone and yes everyone else in my school about 500 students wrote ALCL3 so it made me doubt mine. One or 2 quite able students said that for a question like this the examiner allows both answers so hoping inshAllah that happensI actually think this IS the right ans...as AlCl3 is nt stable...
