Because the electrons involved in making sigma are supposed to have electr0nic density close to joining lines of two nuclei. Hence nuclei is tightly held. Electrons involved in making pibond are below or above the joining lines. Pi bond is m0re diffused and nucleus is nt held tightly.

How many types of bonds present in ethane?
Only sigma bonds are present in ethane. There is one carbon-carbon sigma bond and six carbon-hydrogen sigma bonds in C2H6.
How many sigma bonds does CH3 have?
There are 5 sigma bonds and 1 pi bond in C2H3Cl.
Does Sp3 orbitals have a pi bond?
no, hybrid orbitals cant form pi bonds. they can form only sigma bonds
What types of bonds does 1- butene have?
1-butene can form both pi bonds and sigma bonds. Pi bonds are formed by the overlap of p orbitals, while sigma bonds are formed by the head-on overlap of atomic orbitals. In 1-butene, there are both a C=C double bond and several C-H single bonds contributing to the overall bonding structure.
Why a triple bond should not have 2 sigma bonds?
Sigma bonds lie along the bond axis - between any two atoms you can only have one sigma bond along the axis. Triple bonds encountered in organic chemistry have 1 sigma and two pi bonds( pi bons are "at right angles" to one another and the electron density is between the atoms but does not lie along the bond axis.

What is the difference between single covalent bonds and multiple covalent bonds?
In a single bond there is only a strong sigma bond on the other hand in multiple bond there is a sigma & one or two pi bond, weaker than sigma, which provied addition reactions in a molecule.
How many C-O pi bonds are in water?
None. Water does contains only hydrogen and oxygen, so there is no carbon. Further more, all the bonding in water is sigma bonding; there is no pi bonding.
Are Pi bonds always found in single bonds?
No, pi bonds are not found in single bonds. Pi bonds are formed when p orbitals overlap to share electron density above and below the internuclear axis, creating a second bond in addition to the sigma bond in double or triple bonds.
Are all single bonds sigma bonds why?
A sigma bond is defined as bond with axial symmetry- where the axis runs between the two atoms being bonded. The bond is formed by overlap of atomic orbitals that point along the axis (these can be s orbitals, p d or hybrid orbitals.) In practise the majority of single bonds encountered are sigma bonds, this is particularly true in organic chemistry. However there is no logical reason why thereall single bonds (sharing of a par of electrons) have to be sigma bonds. One example is the bonding in Zeise's salt where a filled d- orbital on the metal atom bonds to an alkene by overlap with a pi antibonding orbital- thisbond has pi symmetry and does not have axial symmetry and there is only one pair of electrons.
Why pi bonds are more diffused than sigma bonds?
Pi bond is considered to be more diffused than Sigma bonds becauseSigma bonds are shorterProbability of finding an electron in a Sigma bond is greater on the inter-nuclear axis.
