What is the bond order of the C-O bond in acetone?

a). 4
b). 1.5
c). 0.5
d). 1
e). 2

in acetone 2 bonds are there in between carbon and oxygen ie at single site so bo is 2 thus e is the correct answer

e).2

To determine the bond order of the C-O bond in acetone, we need to consider the Lewis structure of acetone, which is C3H6O.

In the Lewis structure of acetone, the carbon atom is bonded to two oxygen atoms and has a double bond with one of the oxygen atoms.

The bond order is calculated by counting the number of bonds between atoms and dividing by the number of bond groups.

In the case of the C-O bond in acetone, we have one bond group (double bond) between the carbon and oxygen atoms.

Therefore, the bond order of the C-O bond in acetone is 2.

So the correct answer is e) 2.

To determine the bond order of the C-O bond in acetone, we need to consider the Lewis structure of acetone.

Acetone, also known as propanone, has the chemical formula CH₃COCH₃.

The Lewis structure for acetone can be drawn as follows:

O
//
C - C
// \
H H H

In the Lewis structure, we can see that there is a double bond between one of the carbon atoms (the carbonyl carbon) and the oxygen atom. The other carbon atom is also bonded to the carbonyl carbon and three hydrogen atoms.

The bond order is defined as the number of chemical bonds between two atoms in a molecule. It is calculated by dividing the total number of bonds by the number of bonded pairs of electrons.

In the case of the C-O bond in acetone, there is a double bond between the carbon and oxygen atoms, which means there are two bonded pairs of electrons between them.

Therefore, the bond order of the C-O bond in acetone is 2.

Hence, the correct answer is e). 2.
