Increasing order of dipole moment is

A

`CF_(4) lt NH_(3) lt NF_(3) lt H_(2)O`

B

`CF_(4) lt NH_(3) lt H_(2)O lt NF_(3)`

C

`CF_(4) lt NF_(3) lt H_(2)O lt NH_(3)`

D

`CF_(4) lt NF_(3) lt NH_(3) lt H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
d
`CF_(4)` is symmetrical and non poler `mu = 0`. In `NF_(3)`.the resultant of three `N - F` dipole oppose the effect of lone pairs of electrons of `N` -atom , whereas in `NH_(3)`, the effect of lone pairs of electrons of `N` atom and resultant of three `N - H`dipoles are in the same direction.
Therefore`mu_(NH_(3)) (=1.46 D)gt mu_(NH_(3)`
`mu_(H_(2)O) = 1.85 D`

Arraange the following compounds in increasing order of dipole moment? CH_(3)CH_(2)CH_(3).CH_(3)CH_(2)NH_(2),CH_(3)CH_(2)OH

Polar covalent molecules exhibit dipole moment. Dipole moment is equal to the product of charge separation , q and the bond length d for the bond. Unit of dipole moment is debye. One debye is equal to 10^(-18) esu cm. Dipole moments is a vector quantity. It has both magnitude and direction. Hence, dipole moment of a molecule depends upon the relative orientation of the bond dipoles, but not on the polarity of bonds alone. A symmetrical structure shows zero dipole moment. Thus, dipole moment helps to predict the geometry of a molecules. Dipole moment values can be distinguish between cis- and trans- isomers, ortho, meta and pare-forms of a substance, etc. Q.
