Question

The first transition state in the overall exothermic addition of HBr to propane resembles the intermediate (carbocation). Choose the best phrase to complete the following statement
The second transition states (for addition of $B{r}^{-}$ to the carbocation):

• A. resembles the final product
• B. resembles the $2$-propyl cation
• C. resembles propene
• D. has all carbons almost entirely $s{p}^3$ hybridized

Answer 1

The correct option is B resembles the $2$-propyl cation

As seen in above reaction, the second transition state resembles the 2-propyl cation.
