How was 9701_w15_qp_22 ?

[Manishke]

Messed up the reaction mechanisms. Other than that paper was fine although hydration part was surprising

 

[The Sarcastic Retard]

Oh I didn't give a look on to that, one more mark deducted so now expecting 45

The reaction for propan-2-amine to propanoic acid on the second last page,
what did you guys say for that?

 

[Manishke]

It was supposed to be either Sn1 or Sn2 depending on the halogenoalkane ( primary os tertiary )

I think it was supposed to be hydration. Not sure though

guys someone add the answers for the paper plz

It wasn't either. 2-bromopropane is a secondary halogenoalkane, which makes it hard for us to predict whether it's SN1 or SN2. Simply calling it Nucleophilic Substitution was sufficient.

I think it was supposed to be hydration. Not sure though

It was Dehydration, for some compound to be transformed into Y.

Lol....how about the rest??

rest was fine. I completed the enthalpy cycle using both salts in solution..i think i did it like 'ions in solution'..dunno its wrong or right

No. you have to react it with an acyl chloride and then hydrolyse it,

What abt the bonds formed with different electronegativities

it was permanent dipole-dipole bonds.. as elements with different electronegativities have permanent dipoles..
