Question

EXPLAIN HOW PI AND SIGMA BONDS ARE SIMILAR AND HOW THEY ARE DIFICULT

Answer 1

Explanation:

Sigma bonds are formed by head-on the overlap of atomic orbitals. Whereas pi bonds are formed in addition to sigma bonds by sideways overlapping of atomic orbitals. ... This significant difference in orbital overlap results in sigma bond being stronger thanthe pi bond

Answer 2

Answer:

In organic chemistry sigma bonds (σ) are always the first bond between two atoms, resulting from overlap along the bonding axis (of hybrid orbitals), while pi bonds (π) are second and third bonds resulting from the overlap of p orbitals, above and below (or in front and back of) the bonding axis.
