Question

How many pi and sigma bonds in benzonitrile?

Answer 1

total no of sigma bonds in benzonitrile are 13
In detail,
7 C-C Sigma bonds
5 C-H Sigma bonds
1 C-N sigma bond

notvsure about pi bond
4 pi bonds

Answer 2

In benzonitrile, 5 pi bonds and 13 Sigma bonds are present.

• A clear, colourless liquid with an almond-like odour is what benzonitrile looks like. 161 °F, flash point Denser than water and just slightly soluble in it (8.4 lb/gal). used to create other compounds and as a specialised solvent. The hydrogen in benzonitrile has been substituted with a phenyl group, making it a nitrile that is hydrogen cyanide. It belongs to the benzene family and is a nitrile.

• Atomic orbitals along the internuclear axis must overlap head-on and positively (same phase) in order to form this type of covalent connection. Because the orbitals involved directly overlap, sigma bonds are the strongest covalent bonds. Commonly, the term "electron" refers to the electrons involved in a bond. In general, sigma bonds are used to describe all single bonds. These atomic orbital combinations can be used to create them.

• Pi bonds are created by the sideways positive (same phase) overlap of atomic orbitals in a direction that is perpendicular to the internuclear axis. Atomic orbital axes are parallel to one another when bonds are formed, but they are perpendicular to the internuclear axis when they overlap.

Hence, in benzonitrile, 5 pi bonds and 13 Sigma bonds are present.
