Mark the false statements.
a. a π bond restricts rotation about the bond axis.
b. bonds formed from the overlap of atomic s orbitals are always σ bonds.
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.

false statement are C , F , D.

Explanation:

false statement are C , F , D.

a) triple bond consist of two π bond  and  one sigma bond.

b) in double bond one bond is σ bond and one is π bond.

c) end to end overlapping is in  σ bond and electron density  in  σ bond lie between the nuclei.

true statements are  A, B , E.

π bond restrict rotation is correct and then the statement of bond formation between s orbital is σ bond.

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
