Answer
See explanation below.
Work Step by Step
1
(a) Two sigma bonds comprise a double bond
Ans : False
Correct Statement : A double bond comprises of exactly 1 sigma and 1 pi bond.
2
(b) A triple bond consists of one pi bond and two sigma bonds.
Ans : False
Correct Statement : A triple bond comprises of one sigma bond and two pi bonds.
3
(c) Bonds formed from atomic s orbitals are always sigma bonds.
Ans : True
Reason : As s orbitals have a spherical shape, only sigma bonds are possible from bonds formed by s orbitals.
4
(d) A pi bond restricts rotation about the sigma bond axis.
Ans : True
Correct Statement : Pi bonds are fixed due to bond overlapping. Thus, rotation along sigma bond axis gets restricted.
5
(e) A pi bond consists of two pairs of electrons.
Ans : False
Correct Statement : A pi bond consists of a second pair of electrons after a sigma bond has been previously formed.
6
(f) End-to-end overlap results in a bond with electron density above and below the bond axis.
Ans : False
Correct Statement : End-to-end overlap results in a bond with electron density along the bond axis
