Question

When the hybridization state of carbon atom changes from ${sp}^3$ to ${sp}^2$ and finally to $sp$, the angle between the hybridized orbitals?

• A. Decreases gradually
• B. Decreases considerably
• C. Is not affected
• D. Increases progressively

Answer 1

Answer: (D)

Increases progressively

When the hybridization state of carbon atom changes from $s{p}^3$ to $s{p}^3$ and finally to $sp$, the angle between the hybridized orbitals increases progressively.The bond angles in ${sp}^3,{sp}^2$ and $sp$-hybridisation are ${109}^o,{120}^o$ and ${180}^o$ respectively.
