a. Why are alkanes unreactive?
Because Alkanes have a pi-bond and a sigma-bond and have a stronger attraction whereas alkenes have only pi-bond which is less stronger than pi-sigma bond thus alkanes are unreactive. [NOT JUST: "BECAUSE ALKANES ARE NON-POLAR]
as far as i remember, it was butane which they asked us to make1.
Later they asked how Bromine could be produced. Simple:
C2H6 + Br2 ---> C2H5Br + HBr (I'm not sure if this is correct but no other possibility could be made)
.
This is wrong, butane forms in the termination step when 2 free ethyl radicals react , c2h5• + c2h5• -----> c4h10as far as i remember, it was butane which they asked us to make
yeah i know that butane is made in the terminaion step. i was correcting the question only.This is wrong, butane forms in the termination step when 2 free ethyl radicals react , c2h5• + c2h5• -----> c4h10

They asked about Ethane and Chlorine to form ChloroEthane (something like that) so you just have to write all the Free-Radical Substitution mechanism.

C2H6 + Br2 ---> C2H5Br + HBr (I'm not sure if this is correct but no other possibility could be made)
The decolorising of bromine suggests that Compound Q is unsaturated hydrocarbon and contains the carbonyl group with double bond. Aldehyde and Ketone give a positive test with 2,4-DNPH but only Aldehyde gives a positive reaction with Tollens reagent. So, Ketone is present (C=O)
u stupidnoif u cut the double bond when reacted with hot conc kmn04 u wood get co2 and h20 not a ketone as only two hydrogen atoms are presnet near the double bond when u cut it there is no alkyl group to give a ketone so how can aketone be formed c6h12 no but but 2 ene maybe but not c6h12 it is a simplke test to show u a double bond is present they dont expect u to react with hot conc km04 they didnt say that
bottom line i wrote hexene and hexan 3 one
nd for geometrical isomerism i drew c6h12 cis nd trans
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.
