Question

In the analysis of an organic compound, it was found that it contains 7 carbon atoms, where there are two $C=C$ bonds and one $C\equiv C$ bond. This compound is a hydrocarbon. On structural analysis, it was found that it is covalent in nature and the expected structure is given above. The ratio between the $s{p}^2$ carbons and $s{p}^3$ carbon atoms is:

• A. $2:1$
• B. $1:2$
• C. $1:4$
• D. $4:1$

Answer 1

The correct option is D $4:1$

Number of $s{p}^2$ carbons is $4$.
Number of $s{p}^3$ carbons is $1$.
So, ratio is $4:1$.
