Question

The C-H bond length will be greater when hybridization of carbon is a)dsp3 b)sp c)sp2 d)sp3

Answer 1

the answer will be sp3

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

Bond length is inversely proportional to bond strength. This means that in a single bond there will be lesser strength whereas a double bond will have more strength and a triple bond will be more stronger than a double bond.

Also, it is known that carbon does not have a d-orbital and also it is known that single bond is $sp^{3}$ hybridized, double bond is $sp^{2}$, and triple bond is sp hybridized.

Therefore, strength of C-H bond is weak when it is $sp^{3}$ hybridized and thus it will have greater bond length.
