JEE Mains · Chemistry · STD 11 - 9. Hydricarbon
IUPAC name of the some alkenes are given below. Find out the correct stability order.
A. 2-Methylbut-2-ene
B. cis-But-2-ene
C. 2,3-Dimethylbut-2-ene
D. Prop-1-ene
Choose the correct answer from the options given below :
- A C > A > B > D
- B C > A > D > B
- C B > D > A > C
- D A > B > C > D
Answer & Solution
Correct Answer
(A) C > A > B > D
Step-by-step Solution
Detailed explanation
The stability of alkenes is directly proportional to the number of \(\alpha\)-hydrogen atoms due to hyperconjugation. Let us count the number of \(\alpha\)-hydrogen atoms in each given alkene: A. 2-Methylbut-2-ene: \((CH_3)_2C=CHCH_3\) Number of \(\alpha\)-hydrogen atoms =…
