Question

Mimosine is a natural product found in large quantities in the seeds and foliage of some legume plants. It has been shown to cause inhibition of hair growth as well as hair loss in mice.

a. What functional groups are present in mimosine?

b. Give the hybridization of the eight carbon atoms in mimosine.

c. How manyand bonds are found in mimosine?

Short answer

1. Mimosine is a chemical made up of carboxylic acid, amine, ketone, and alcohol.
2. The chemical "mimosine" is made up of six carbon atoms with sp² hybridization and two carbon atoms with sp³ hybridization.
3. Mimosine has $24\sigma$bonds, $4\pi$bonds.

Step-by-step solution

Subpart (a) The functional groups present in mimosine.

Here, four sorts of functional groups are present in the structure.

The first carboxylic acid, since the carboxyl group has an "OH group" linked to it,

The second amine, since a "NH₂ group" is attached to a "HC group".

As "O " is connected to the carbon atom by a double bond, this is the third type of group ketone.

The fourth group is alcohol since the carbon atom is connected to "OH ".

Subpart (b) The hybridization of the eight carbon atoms in mimosine.

The hybridization is based on a modified LE model of the observation of peculiar atomic orbitals in the formation of molecules.

The number of distinct atoms to which a carbon atom is linked determines the hybridization.

To determine the hybridization of the eight carbon atoms in the given molecule "mimose," one must first count how many bonds each carbon atom has individually, then number the carbon atoms in the molecular structure.

(as presented below)

The first carbon atom (¹C) has three bonds, which tells us that the hybridization of the first carbon atom will be sp².

$-\text{'}{\text{'}}^2{C}^{\text{'}\text{'}}$has four bonds which explains the hybridization issp³ .

$-\text{'}{\text{'}}^3{C}^{\text{'}\text{'}}$will have sp³

$-\text{'}{\text{'}}^4{C}^{\text{'}\text{'}}$will havesp²

$-\text{'}{\text{'}}^5{C}^{\text{'}\text{'}}$will havesp²

$-\text{'}{\text{'}}^6{C}^{\text{'}\text{'}}$will havesp²

$-\text{'}{\text{'}}^7{C}^{\text{'}\text{'}}$will havesp²

$-\text{'}{\text{'}}^8{C}^{\text{'}\text{'}}$will havesp²

Subpart (c) The number of  and  bonds are found in mimosine.

Sigma bonds are found in all single bonds in organic compounds, and every double or triple bond has one sigma bond.

In addition to the sigma bond, the double bond has a pi bond.

From the figure below, Mimosine has 24 sigma bonds, 4 pi-bonds.
