Question

a) i) The dipole moment of HBr is 2.602 × 10^(-30) C m and its bond length is
141 pm. Calculate its percentage ionic character.
ii) Draw a rough sketch of total molar polarization versus 1/temperature
curve for CO2 and SnCl2.

b) i) Nitrogen dioxide can exist as both monomer and dimer. Based on
magnetic characteristics, how can you differentiate between the two?
ii) For 2, 3–Dichlorobutane, draw the structures for the enatiomers and meso
forms.
