Question

In the compound \(^1\text{CH}_2 = ^2\text{CH}-^3\text{CH}_2-^4\text{CH}_2-^5\text{C}\equiv ^6\text{CH}\), The \(C_2-C_3\) bond is of type

• A. \(sp-sp^2\)
• B. \(sp^3-sp^3\)
• C. \(sp-sp^3\)
• D. \(sp^2-sp^3\)

Hint:

Double bonded carbon is $sp^2$ and saturated carbon is $sp^3$.

Answer 1

The Correct Option is D

Step 1: Count sigma bonds
$C_2$ has three sigma bonds (two C, one H), so $sp^2$. $C_3$ has four sigma bonds, so $sp^3$.

Final Answer:
Option (D). \[ \boxed{\text{(D)}} \]
