Question

question 6
where is the electron density concentrated in sigma bonds? (reference p 265 of your textbook.)
a between the two bonding atoms nuclei
b split to both to the outside volume of the bonding nuclei
c focused to the outside of the electrons of the bonding nuclei
d split to both outside volume of the bonding electrons

Explanation:

A sigma bond is formed by the head - on overlap of atomic orbitals. In this type of overlap, the electron density is concentrated along the internuclear axis, which means it is concentrated between the two bonding atoms' nuclei. Options B, C, and D do not accurately describe the electron - density distribution in a sigma bond.

Answer:

A. Between the two bonding atoms nuclei
