Question

Number of pi bonds in aniline is -

Answer 1

Hint: The atoms in the chemical molecule are bonded to each other by a chemical bond. Different types of chemical bonds were present in the molecule. The covalent bond is formed by sharing of electrons between the two atoms and overlapping of orbitals side by side leads to the formation of a pi-bond.

Complete answer:
Aniline is a chemical compound and also it can be classified as a base.
Due to the lone pair of electrons on nitrogen atoms, aniline easily donates a lone pair of electrons or it can abstract the proton easily, hence it is considered as a base.
The molecular formula of aniline is \[{C_6}{H_5}N{H_2}\]
Aniline is the derivative of benzene, one of the hydrogen atoms in the benzene is replaced by an amine group. Due to the presence of amine which is an electron releasing group, deactivates the ring towards electrophilic aromatic substitution.
As the benzene is aromatic, aniline can also be considered as aromatic.
The aromatic ring contains three double bonds and three single bonds.
Pi-bonds are weak and formed by the sideways overlap of orbitals.
Pi-bonds were represented by \[\pi \] , these are weak bonds compared to sigma bonds.
The double bond indicates the presence of one sigma bond and one pi bond.
In aniline there are a total of \[3\] pi bonds.

Note:
The double bond contains one sigma bond and one pi-bond, whereas the triple bond contains one sigma bond and two pi-bonds. The benzene ring contains three pi-bonds and six sigma bonds Both, sigma and pi-bonds are the covalent bonds.
