Question

Ethylene is converted to ethane in the presence of $Ni$ at ${300}^{0}C$ . In this reaction the hybridization of carbon changes from :

• A. $sp$ to $s{p}^2$
• B. $s{p}^2$ to $s{p}^3$
• C. $s{p}^3$ to $sp$
• D. $sp$ to $s{p}^3$

Answer 1

Answer: (B)

$s{p}^2$ to $s{p}^3$

In ethylene $C_2{H}_4$, $C$ atom is $s{p}^2$ hybridised
In ethane $C_2{H}_6$, $C$ atom is $s{p}^3$ hybridised as it does not contain double bonds

Option B is correct.
