Question

9.

option C and D carbocations are secondary carbocation. so these carbocations tends to rearrange to form stable carbocation.

secondary carbocation rearranges to more stable tertiary carbocation.

we know, as migration affinity of -CH3 group is greater than -H.

so option C structure leads to the -CH3 shift and option D structure leads to the -H shift.

so option C is the answer.

10.

option C is the answer.

becasuse phosfate diester part contains R3 part which is positive charged ammonium part. so this more polar.

R1 and R2 are hydrofobic part in this structure.
