The rule for hybridization: All sigma bonds (single bonds and only one bond in double or triple bonds) and lone pairs (nonbonding pairs) are found in hybrid orbitals. We understand from this statement that hybrib orbitals cannot form pi bonds.
Boron (B) (atomic no:5) has 3 valence electrons and form 3 single bonds and no pi bond. Therefore it is impossible for B to make bonds without hybridization.
Nitrogen (N) (atomic no: 7) has 5 valence electrons. Normally it can form 3 sigma bonds to complete its octet. Note that although B also have 3 sigma bonds it can not complete its octet. In such a case nitrogen can not form any bond without hybridization like in the case of ammonia NH3. Together with the non bonding pair of N , the type of hybridization of N is sp3 when all the bonds of N are single (sigma) bonds.
On the other hand , N can be form 1 double bond like in the case of nitrate ion, NO3^-. 2 of the O atoms are bound to N by single bonds and one O atom is bound to N atom by a double bond (one sigma and one pi). In such a case since pi bonds are formed without hybridization, 2 of the bonds of N are formed by hybridization and 1 of them is formed without hybridization. Together with the non bonding pair of N , the type of hybridization of N is sp2 when it forms one double bond.
In some cases N can form a triple bond, like in the case of cyanate ion CN^-. There is a triple bond between C and N atoms. One of them is sigma the others are pi bonds. This time 2 bonds are formed without hybridization. Together with the non bonding pair of N , the type of hybridization of N is sp when it forms one triple bond.
Oxygen (O) (atomic no: 8) has 6 valence electrons. Normally it can form 2 sigma bonds to complete its octet. In such cases oxygen can not form any bond without hybridization like in the case of ammonia H2O. Together with the two non bonding pair of O , the type of hybridization of O is sp3 when all the bonds of O are single (sigma) bonds.
However , O can be form 1 double bond like in the case of ozone molecule, O3 . 1 of the O atoms are bound to the central O atom by a single bond and the other O atom is bound to Central O atom by a double bond (one sigma and one pi). Since pi bonds are formed without hybridization, 2 of the bonds of O are formed by hybridization and 1 of them is formed without hybridization. Together with the non bonding pair of O , the type of hybridization of O is sp2 when it forms one double bond.
Remark: As you may notice, in H2O, O has two nonbonding pairs, but in O3, the central O has 1 nonbonding pair. One of them is used to make a coordinate covalent (dative) bond with the O atom to form a single bond by completing its octet vacancy.
As a summary; When N forms a double bond, 1 bond (1 pi)
When N forms a triple bond, 2 bonds (2 pi)
When O forms a double bond, 1 bond (1 pi)
cannot be made by by hybridization.
O cannot form a triple bond.

What is the hybridization at each carbon atom in the propylene molecule?
sp3
What is the hybridization of the central atom of each of H2O COH2 and PCl5?
H2O is sp3 PCl5 is sp3d COH2 is sp2
Haw many bonds can each carbon atom make?
Carbon makes 4 bonds.
How many covalent bonds are in SiO2?
It has 4 covalent bonds which constitute 2 double bonds with each oxygen atom.
Each carbon atom can form a total of?
four bonds maximum
What is VSEPR central atom hybridization of c4h10?
There are 4 carbon atoms, which each individually act as a central atom since they are surrounded entirely by the hydrogen atoms. Each carbon forms 4 sigma bonds, therefore, each carbon atom has a hybridization state of sp^3.
How many bonds can each atom make without hybridization P3s23p3?
Three is the answer expected. Higher valences of phosphorus, in PCl5 for example can be explained by hybridisation although this method is not the only explanation.
What is the hybridization of the central atom in each of SO3?
Sulfur in sulfur trioxide undergoes sp2 hybridization.
What is the hybridization at each carbon atom in the propylene molecule?
sp3
What is the hydbridization of central atom of pcl5?
The central atom P is bonded to the five chlorine atoms by five single covalent bonds. So, the total number of single bonds is 5. The hybridization must be among one s orbital, three p orbitals and one d orbital each of which has a half filled orbital to share with the half filled orbital of each chlorine atom. So the hybridization can be written as sp3d. 1s, 3p and 1 d, a total of 5. An easy way to find the hybridization is to count the number of bonds including the unshared electrons around the central atom. For double or triple bond count only one. If the total number of bonds including the number of unshared electron pairs is 6, then the hybridization will be sp3d2, a total of 6.
How many bonds does each atom have in graphite?
Each atom has three covalent bonds in graphite.
How many bonds can each carbon atom form?
They can each form four bonds.
Which molecules show an appropriate number of bonds around each carbon atom?
The molecule that shows an appropriate number of bonds around each carbon atom should show the carbon atom with 4 total bonds.
How many bonds can each atom of carbon and each atom of hydrogen form?
Carbon 4Hydrogen 1
What is the hybridization of the central atom of each of H2O COH2 and PCl5?
H2O is sp3 PCl5 is sp3d COH2 is sp2
What type hybridization occurs in the orbital of a carbon atom particle in a triple bond whit another carbon atom?
sp hybridisation. Leaving two p orbitals on each C atom available to form pi bonds. There are then three bonds, a sigma bond between the C atoms formed by overlap of the sp hybrid orbitals, and two pi orbitals formed by overlap of the p orbitals
Haw many bonds can each carbon atom make?
Carbon makes 4 bonds.
