B) 2
C) 3
D) 4
Show Answer
Answer:
Correct Answer: C
Solution:
$ \underset{\text{3-hexyne-1-ene}}{\mathop{\overset{1,}{\mathop{CH_2}},=\overset{2,}{\mathop{CH}},-\overset{3,}{\mathop{C}},\equiv \overset{4}{\mathop{C}},-\overset{5}{\mathop{CH_2}},-\overset{6,}{\mathop{CH_3}},}}, $ Three $ \pi $ bonds.
