Q. Which of the following molecules represents the order of hybridisation $sp^2$, $sp^2$, sp, sp from left to right atoms ?
A) $CH_2=CH-CH=CH_2$
B) $CH_2=CH-C\equiv CH$
C) $HC\equiv C-C\equiv CH$
D) $CH_3-CH=CH-CH_3$
Explanation
[Solution] In $CH_2=CH-C\equiv CH$ the two alkene carbons are $sp^2$ and the two alkyne carbons are sp. Answer (2).
