Question

For this question please enter the number of sigma (σ) and pi (π) bonds (e.g. 0,1,2,3,4, etc). How many sigma and pi bonds, respectively, are in this carboxylic acid? H2CCHCH2COOH. σ bonds and π bond(s). How many sigma and pi bonds, respectively, are in this organic molecule (an amine)? HCCCH2CHCHCH2NH2. σ bonds and π bond(s). How many sigma and pi bonds, respectively, are in this organic molecule (an alcohol)?

Answer 1

Answer:

Explanation:

find the solution below

Answer 2

Answer:

H2CCHCH2COOH there are two pi bonds and eleven sigma bonds

HCCCH2CHCHCH2NH2 there are three pi bonds and fifteen sigma bonds

H3CCH2CH2CH2OH there are no pi bonds but there are fourteen sigma bonds

Explanation:

Sigma and pi bonds are both covalent bonds. Sigma and pi bonds are formed by different orientations of the overlap of atomic orbitals. A sigma bond, σ, resembles a similar "s" atomic orbital, and a pi pond, π, has the same orbital symmetry of the p orbital.

A Sigma bond (σ bond) is covalent bond formed by overlap of atomic orbitals and/or hybrid orbitals along the bond axis while a Pi bond is formed by the sidewise positive (same phase) overlap of atomic orbitals along a direction perpendicular to the internuclear axis. During the formation of π bonds, the axes of the atomic orbitals are parallel to each other whereas the overlapping is perpendicular to the internuclear axis.

In the compounds mentioned in the question, One could decipher the number of sigma or pi bonds by counting the number of bonds in the compound. Multiple bonds are pi bonds while single bonds are sigma bonds
