Assertion (A): Double bond in carbon molecule is consist of two pi-bonds.
Reason (R): Due to presence of four electrons in two pi-molecular orbitals.
In the light of the above statements, choose the most appropriate answer from the options given below:
View answer and explanation
Correct option: D
Both (A) and (R) are correct and (R) is the correct explanation of (A)
The correct answer is D (Both (A) and (R) are correct and (R) is the correct explanation of (A)) because the carbon molecule () indeed has a double bond consisting of two pi-bonds, which is due to the presence of four electrons in two pi-molecular orbitals.
