ion the formal charge on the oxygen atom of P−O bond is ___Detailed Solution: Question 3
ion, formal charge on each 
-atom of 
Which of the following contains both covalent and ionic bond?
Detailed Solution: Question 4
Which of the following species is a radical?
Detailed Solution: Question 5
Odd electrons (seven valency electrons of nitrogen and eight valency electrons of oxygen), so this species work as radical. 
, the total electrons are 
(even), in case of nitro ion, total valency electrons are 
(even), In case of cyanide ion, total valency electrons are 
(even).The correct order in which the O − O bond length increases in the following is-
Detailed Solution: Question 6
Which of the following Lewis dot structure of 
is incorrect?
Detailed Solution: Question 7
can be represented as
(Incorrect structure)
The molecules 
and 
are both covalent compounds, but 
is non polar whereas 
is polar. The reason for this is
and are both covalent compounds, but is non polar whereas is polar. The reason for this isDetailed Solution: Question 8
hence it is non polar.
is pyramidal
hence it is polar.The number and type of bonds in ion in 
are:
are:Detailed Solution: Question 9
is 
and two 
bondsIn 
and 
, the number of lone pairs on Xe are respectively
Detailed Solution: Question 10
Total number of valence electrons of 
, two electrons shared with 
atoms, 6 electrons left hence 3 lone pairs, in 
shared with 
atoms 4 left hence 2 lone pairs; in 
shared with 
atoms 2 left hence 1 lone pair.The number of 
molecules participating in hydrogen bonding in 
is/are
Detailed Solution: Question 11
is the represenation of given compound.The maximum number of H-bonds in which water molecule can participate is
Detailed Solution: Question 12
molecule, two H-bonds are formed with 
atom and two are formed with 
atoms of the 
molecule.Which of the following molecules has highest dipole moment?
Detailed Solution: Question 13
and 
is zero because these are symmetrical molecules. Dipole moment of 
is greater than 
.
Which of the following has least covalent P − H bond?
Detailed Solution: Question 14
bond will have ionic character due to electron attracting tendency of P-carrying positive charge and least covalent.Which one of the following has longest covalent bond distance?
