may some body plz answer this question for me ?
any explaination is greatly appreciated
"Briefly explain why 2-bromopropane is the main product rather than 1-bromopropane in the reaction of HBr with propene"

well tomorrow how willl you come? pick me up in activa

What to learn ?

is it a past paper ? if yes just state the anti markonikovs rule :3

No I dont

IDK .

No I dont

well here goes nothing its As i guess
markonikovs rule " during electrophylic addition of alkenes the hydrogen atoms attach to the carbon atom with the most hydrogen atoms already attached"

http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s04_qp_4.pdf Q2c(i) i get the answer but cant we state the size of carbon atom being smaller than silicon as a valid reason

Yes in a sense you can, however the better reason will be that C does not have empty D orbitals. just remember this one line statement it won't kill you

http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s05_qp_4.pdf 3 a (i) how do we know that the reaction has a higher activation energy?

This my friend is indeed a good question. I would like to know the answer to this as well.. lol How can we determine the Ea? does endothermic reaction show high Ea reactions? or is it the magnitude? no clue.

I think the answer to this comes from the fact that reaction 1 needs to be heated to a higher temperature.. yaar wo AS wala jo tha.. Boltzman Temeperature wala # of particles/energy graph. Increasing temperature increases the number of particles with enough activation energy.
