NEETChemistryHaloalkanes and HaloarenesMCQ+4 / −1
Which one is most reactive towards SN1 reaction?
- AC6H5CH(C6H5)Br
- BC6H5CH(CH3)Br
- CC6H5C(CH3)(C6H5)Br
- DC6H5CH2Br
View written solutionFree
Correct answer: C
SN1 reactions involve the formation of carbocations, hence higher the stability of intermediate carbocation, more will be reactivity of the parent alkyl halide. The tertiary carbocation formed from (c) is stabilized by two phenyl groups and one methyl group, hence most stable.
