JEE PYQ: Hydrocarbons Question 6
Question 6 - 2021 (17 Mar Shift 2)
The total number of C – C sigma bond/s in mesityl oxide ($\text{C}6\text{H}{10}\text{O}$) is _______ (Round off to the Nearest Integer).
Show Answer
Answer: (5)
Solution
Mesityl oxide: $\text{H}_3\text{C}-\overset{\sigma}{\text{C}}=\overset{\sigma}{\text{CH}}-\overset{\sigma}{\text{C}}(-\overset{\sigma}{\text{CH}_3})(-\text{CH}_3)=\text{O}$. $\therefore$ C-C $\sigma$ bonds = 5.
