NEET Solved Paper 2018 Question 18
Question: Which of the following molecules represents the order of hybridisation $ s{p^{2}}\text{, s}{p^{2}}\text{, sp, sp} $ from left to right atoms? [NEET - 2018]
Options:
A) $ C{H_2}\text{=CH-CH=C}{H_2} $
B) $ C{H_2}\text{=CH-C}\equiv CH $
C) $ HC\equiv \text{C-C}\equiv CH $
D) $ C{H_3}\text{-CH=CH-C}{H_3} $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \overset{sp^{2}}{\mathop{C{H_2}}},=\overset{sp^{2}}{\mathop{CH}},-\overset{sp}{\mathop{C}},\equiv \overset{sp}{\mathop{CH}}\ $
Number of orbital require in hybridization = Number of $ \sigma -bonds $ around each carbon atom.
