Answer:
c. a triple bond consists of one π bond and two σ bonds.
d. end-to-end overlap of orbitals results in a bond with electron density above and below the bond axis.
e. a π bond consists of two pairs of electrons.
f. two σ bonds comprise a double bond.
Explanation:
Mark the false statements.
a. a π bond restricts rotation about the bond axis. TRUE.
b. bonds formed from the overlap of atomic s orbitals are always σ bonds. TRUE.
c. a triple bond consists of one π bond and two σ bonds. FALSE. A triple bond consists of one σ bond and two π bonds.
d. end-to-end overlap of orbitals results in a bond with electron density above and below the bond axis. FALSE. End-to-end overlap of orbitals results in a bond with electron density along the bond axis.
e. a π bond consists of two pairs of electrons. FALSE. A π bond consists of one pair of electrons.
f. two σ bonds comprise a double bond. FALSE. A double bond is comprised of one σ bond and one π bond.
A bond is formed when atomic orbitals overlap with each other.
A bond is formed by the overlap of orbitals. A sigma bond is formed by end to end overlap of atomic orbitals while a pi bond is formed by side by side overlap of atomic orbitals. In a pi bond, the electron density is located above and below the bond axis of the bond while in a sigma bond, electron density is located along the axis of the bond.
