CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313839 \(\mathrm{H}_{2} \mathrm{O}\) is dipolar, whereas \(\mathrm{BeF}_{2}\) is not. It is because

1 the electronegativity of F is greater than that of \(\mathrm{O}\)
2 \(\mathrm{H}_{2} \mathrm{O}\) involves hydrogen bonding whereas \({\rm{Be}}{{\rm{F}}_{\rm{2}}}\) is a discrete molecule
3 \(\mathrm{H}_{2} \mathrm{O}\) is linear and \(\mathrm{BeF}_{2}\) is angular
4 \(\mathrm{H}_{2} \mathrm{O}\) is angular and \(\mathrm{BeF}_{2}\) is linear

313840 Given below are two statements:
Statement A :
Dipole moment is a vector quantity and by convention it is depicted by a small arrow with tail on the negative centre and head pointing towards the positive centre.
Statement B :
The crossed arrow of the dipole moment symbolizes the direction of the shift of charges in the molecule.

1 Both Statement A and Statement B are correct.
2 Statement A is correct but Statement B is incorrect.
3 Statement A is incorrect but Statement B is correct.
4 Both Statement A and Statement B are incorrect.
