Current Question (ID: 10824)

Question:

$\text{The cylindrical shape of an alkyne is due to the presence of-}$

Options:

1. $\text{Three sigma C-C bonds}$
2. $\text{Three } \pi \text{ C-C bonds}$
3. $\text{Two sigma C-C and one } \pi \text{ C-C bonds}$
4. $\text{One sigma C-C and two } \pi \text{ C-C bonds}$ (Correct)

Solution:

$\text{Hint: Alkyne contains a triple bond.}$ $\text{In alkynes, C≡C is present, in such a bond one sigma and two } \pi \text{ C-C bonds are present. Sigma bond is formed by sp-hybrid orbitals overlap with each other, whereas } \pi\text{-bonds are formed by unhybridized p orbitals overlapping with each other.}$ $\text{Hence, it shows a cylindrical shape.}$
