Which of following is correct
A
PH3<AsH3<SbH3< NH3 order of boiling point
B
D2O(s) > H2O ( 
) order of density
) order of density
C
Mn>Ca>Sr>Rb order of metallic bond strength
D
H2< CO2< H2O increasing order of intermolecular forces of attraction
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(b, c, d)
SbH3 > NH3 > AsH3 > PH3 ( order of B.Pt)
As D2O has higher molecular mass than H2O so its density is more.
Mn 
4s23d5
Ca 
[Ar] 4s2
Sr 
[Kr]5s2
Rb 
[Kr]5s1
H2 
weak VDW forces
CO2 
weak VDW force but stronger than H2.
H2O 
H-bonding.
