Question

Which of the following molecules have a non-zero dipole moment? 1, 3, and 5 1, 2, 3, and 5 1 only 4 only 5 only Which of the following are correct? Covalent network solids have low melting points, are soft, and usually are poor conductors of electricity. Ionic solids usually have high melting points, do not conduct electricity in the solid state, and are usually brittle. Metals have melting points ranging from low to very' high, are good conductors of electricity, and are ductile and malleable. Molecular solids are generally hard, with high melting points, and are poor of electricity. none of them 1 and 2 2 and 3 2 and 4 1 and 4

Explanation / Answer

22)
1) Due to lone pair on S , it is unsymmetrical in shape. hence dipole moment is non zero
2) It is linear in shape. Net dipole moment 0
3)Due to lone pair on Se , it is unsymmetrical in shape. hence dipole moment is non zero
4) It is linear in shape. Net dipole moment 0
5) Due to lone pair on S , it is unsymmetrical in shape. hence dipole moment is non zero
