Four sigma bonds. One between the carbon and each hydrogen in turn.
I am guessing you mean how many. NH3 contains 3 sigma bonds. There is no other type of sigma bonds.
These are the sigma covalent bonds which formed the bonds as sp3 hybridized orbitals.
Sigma and pi bonds are nucleophiles. Pi bonds are more nucleophilic than sigma. Electrphilic is not a term usually associated with either sigma or pi bonds.
sigma bonds=9 and pi bonds=2
39 sigma and 6 pi bonds

sp3 or 4 sigma bonds
These are the sigma covalent bonds which formed the bonds as sp3 hybridized orbitals.
Overlap of each hydrogen 1s orbital with four sp3 hybridized orbitals yielding four sigma bonds.
there are 6 sigma bonds in a benzene ring Correction: There are 6 sigma carbon-carbon bonds...but there are also 6 carbon-hydrogen sigma bonds. Thus there are twelve sigma bonds in a benzene ring.
26 sigma bonds
12 sigma bonds.
there are 97 sigma bonds and 11 pi bonds
26

3 sigma bonds!
There are 5 sigma bonds and 1 pi bond in C2H3Cl.
