What is a sigma bond Describe with the aid of a diagram how the overlap of two half filled 1 s orbitals produces a sigma bond?
a sigma bond is a one to one bond that is the weakest type of bond. the two filled orbitals form a single bond to hold the two elements together
How many sigma bonds can the two sets of 2p orbitals make with each other?
Assuming you mean two sets of p orbitals on adjacent atoms only one sigma bond can be formed, by the p orbitals that point between the atoms to form an axial bond. The lobes that are at right angles , ( two unused p orbitals on each atom) could form pi bonds.
What is the best description of the carbon-carbon bonds in ethene C2H4?
Two sp2 orbitals overlap to form a sigma bond, and two 2p orbitals overlap to form a pi bond.
What two orbitals overlap in a single bond?
overlapping that occurs along the orbital axis of 2 atomic orbitals is known as linear overlapping and these orbitals are called sigma atomic orbitals therefore these bonds are known as sigma bonds
Why can't you have two carbon atoms joined by 4 covalent bonds?
A carbon-carbon quadruple bond does not exist because that much electron density between the two nuclei would cause too much electrostatic repulsion. This prevents the electrons from grouping so tightly in such a small space. To find the actual bond order of a carbon-carbon bond, one would have to draw out a molecular orbital diagram. One would find that the molecular orbitals caused by the 1s and 2s atomic orbitals would have both bonding and antibonding orbitals filled, making them irrelevant to finding the bond order. The 2p orbitals give rise to two degenerate bonding pi orbitals, both of which are filled. Since there are no antibonding orbitals filled above the pi orbitals, the bond order is two.
A bond forms when two atomic or hybrid orbitals overlap to form a single bond A bond forms when two p orbitals overlap in a double or triple bond?
sigma, pi

What two atomic orbitals or hybrid atomic orbitals overlap to form the c equals c bond in ethene?
sp2 hybrid orbitals overlap.
What means p bond?
A p bond is the result of the sideways overlap of two parallel p orbitals.

What is a sigma bond Describe with the aid of a diagram how the overlap of two half-filled 1 s orbitals produces a sigma bond?
Sigma bond is nothing but the overlap of half filled atomic orbitals along the nuclear axis. In the case of two half filled 1s orbitals... the electrons approch each other as well as repells... because of nucleus(attraction) and the other electron(repulsion). so they stay in the middle of these two opposing forces and forms a bond so called sigma bond.
What is covalent bond theory?
A covalent bond forms when the orbitals of two atoms overlap and a pair of electrons occupy the overlap region is called covalent bond theory
What happends when two atoms are chemically combined?
you have a chemical bond that is either ionic or covalent or something between the two extremes. Atoms become more stable when they are combined. Valence electron form hybridized orbitals with empty orbitals to form a bond in covalent bonds.
What is the of h2so4?
The hybridisation of sulfur is sp3. The structure is often drawn with two double bonds, with double bond formed from d orbitals on sulfur and p orbitals on oxygen. This is the Pauling valence bond 1940's approach. More recent work suggests that the involvement of d orbitals is minimal.
