Hydrocarbons 2 Question 28
28. In the compound, $>\mathrm{H}$, the $\mathrm{C} 2-\mathrm{C} 3$ bond is of the type
$(1999,2 \mathrm{M})$
(a) $s p-s p^{2}$
(b) $s p^{3}-s p^{3}$
(c) $s p-s p^{3}$
(d) $s p^{2}-s p^{3}$
Show Answer
Answer:
Correct Answer: 28. (b)
Solution:
- According to the IUPAC conventions, compound can be numbered as:
$$ \mathrm{H}{2} \stackrel{1}{\mathrm{C}}=\stackrel{2}{\mathrm{C}} \mathrm{H}-\stackrel{3}{\mathrm{C}} \mathrm{H}{2}-\stackrel{4}{\mathrm{C}} \mathrm{H}_{2}-\stackrel{5}{\mathrm{C}} \equiv \stackrel{6}{\mathrm{C}}-\mathrm{H} $$
Here, $\mathrm{C}-2$ is $s p^{2}$ and $\mathrm{C}-3$ is $s p^{3}$-hybridised.
