Question

1, 3, 5, 7 - Octatetraene contains $$\underline X $$  $$\sigma $$ - bonds and $$\underline Y $$  $$\pi $$ - bonds. $$'X'$$  and $$'Y'$$  are respectively

A. 23, 4
B. 17, 4  
C. 18, 5
D. 33, 2
Answer :   17, 4
Solution :
$$C{H_2} = CH - CH = CH - CH$$       $$ = CH - CH = C{H_2}$$
No. of $$\sigma $$ - bonds = 17, No. of $$\pi $$ - bonds = 4
