Account for the following : (i) Phenol has a smaller dipole moment than methanol.

NH3 has larger dipole moment

the structue of BeH2   H - Be - H The bond are polar but the dipole moment e]which is developed towards one hydrogen is cancelled by other and so it dipole...

The dipole moment of NH3 is higher in comparison to NF3.  REASON  The F i.e. fluorine is more electronegative than N and pulls the electrons . As the number NF bonds is...

(i) Because phenol has electron attracting benzene ring. (ii) Resonance and +ve charge oxygen does not have tendency to accept a proton.

Electric dipole moment, p = 4 × 10−9 C m Angle made by p with a uniform electric field, θ = 30° Electric field, E = 5 × 104 N C−1 Torque acting...

 (a) Order of dipole moment NH3 > PH3 > AsH3 > SbH3 (Based upon electronegativity)

(i) Dipole moment is a product of charge and distance. Since chlorobenzene has lower magnitude of negative charge on Cl atom and shorter C—Cl bond than cyclohexyl chloride due to...

P = 3 x 10-8cm ; E =104N/C  At stable equilibrium (θ1 ) = 0°  At unstable equilibrium (θ2) =180°  Work done in rotating dipole is given by:  W = PE (cosθ1 - cosθ2 )   =...

Dipole moment P =5 x10-4Cm. Electric field (E) =104N/C At stable equilibrium θ1 = 0° At unstable equilibrium θ2 =180° Work done = - PE (cosθ2 - cosθ1) = -(5 x 10-8 ) (104 )...

Dipole moment of an electric dipole is the product of either of charge and the length of dipole. It is a vector quantity. vector P = q(2vector a)
