Answer:
Following are the answer to this question:
Step-by-step explanation:
The most stable carbocation is:
![C_9H^(+)_(11)](https://img.qammunity.org/2021/formulas/chemistry/college/4ovm9s5nt1mt7mh36vn2wupujvxlct0jdk.png)
- The means of
is a hydrocarbon with
, which is needed to find the double bonds.
- The formula for calculating the unsaturation hydrocarbons are:
Degree of the unsaturation
![= (2C+2+N-X-H)/(2)](https://img.qammunity.org/2021/formulas/chemistry/college/rbb7li3df767epbzvkikn2rv9vrdgk56ct.png)
Where,
C=9, N=0, X=0, H=12
![\ Degree \ of \ the \ unsaturation= (2* 9+2+0-0-12)/(2)](https://img.qammunity.org/2021/formulas/chemistry/college/94kh29j5qg2q2kui5a2syvt201q25iwlv2.png)
![= (20-12)/(2)\\= (8)/(2)\\=4](https://img.qammunity.org/2021/formulas/chemistry/college/15uhf163sxk0x63ynmpggh2j86w9z3ed71.png)
which means 3 double bonds and 1 ring.
