Detailed Solution: Question 5
The electronegativity difference between 
and 
is greater than that between 
and 
yet the dipole moment of 
is larger than that of 
. This is because
and is greater than that between and yet the dipole moment of is larger than that of . This is becauseDetailed Solution: Question 6
the atomic dipole (orbital dipole due to lone pair) and bond dipole are in the same direction whereas in 
these are in opposite direction so in the former case they are added up whereas in the latter case net result is reduction of dipole moment. It has been shown in the following figure :
The dipole moments of diatomic molecules 
and 
are 
and 
, respectively while their bond distances are 
and 
, respectively. This indicates that
and are and , respectively while their bond distances are and , respectively. This indicates thatDetailed Solution: Question 7
