• 9

Answer 1

7

Explanation:

\[\begin{array}{cc}
\ce{CH3 - C - CH3}\phantom{..}\ce{CH3 - CH2 - C - H}\phantom{..}\ce{CH2 = CH - CH2 - OH}\\
|| \phantom{.......................}||\phantom{.......................}\\
\ce{O}\phantom{.......................}\ce{O}\phantom{.......................}\end{array}\]

\[\ce{CH2 = CH - O - CH3}\]

Total = 7
