I am guessing you mean how many. NH3 contains 3 sigma bonds. There is no other type of sigma bonds.
Four sigma bonds. One between the carbon and each hydrogen in turn.
39 sigma and 6 pi bonds
All covalent bonds contain one sigma bond.
No, pi bonds are generally more nucleophilic than sigma bonds because of the electron density distribution along the pi bonds, which allows for better overlap with nucleophilic species. Sigma bonds, on the other hand, are more localized between bonding atoms and have lower electron density, making them less reactive towards electrophiles.
No, sulfur tetrafluoride (SF4) does not contain delocalized pi bonding. In SF4, the sulfur atom forms four sigma bonds with fluorine atoms and has one lone pair of electrons. The bonding in SF4 is primarily characterized by localized sigma bonds rather than delocalized pi bonds, as the molecular structure does not allow for resonance or electron delocalization.
There are three bonds.They are polar covalent bond.
Ammonia, NH3, contains covalent bonds. The bonds between nitrogen and hydrogen atoms are formed by the sharing of electrons, making them covalent bonds.
Four sigma bonds. One between the carbon and each hydrogen in turn.
Yes, sigma and pi bonds can be found in the same molecule. Sigma bonds are formed by head-on overlapping of atomic orbitals, while pi bonds are formed by sideways overlap of p-orbitals. Double and triple bonds, for example, contain both sigma and pi bonds.
No, NH3 does not contain a nonpolar covalent bond. The bonds in NH3, which are between nitrogen and hydrogen atoms, are polar covalent because nitrogen is more electronegative than hydrogen, causing an uneven distribution of electrons.
there are 97 sigma bonds and 11 pi bonds
26 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.

39 sigma and 6 pi bonds
There are 22 sigma bonds and 12 pi bonds in anthracene, while a fullerene such as C60 does not contain any sigma or pi bonds as it is a molecule composed entirely of carbon atoms bonded in a spherical structure called a buckyball.
AsI3 has 3 iodine atoms bonded to the central arsenic atom. Each single bond consists of a sigma bond, so there are 3 sigma bonds in total. AsI3 does not contain any pi bonds.
