Question

27) Identify the compound with the largest dipole moment in the gas phase. - A) Cl2 B) NaBr C) BrF D) CCl4E ) HCI 28) Choose the bond below that is most polar. A) N-O B) C-F C) C-P ORD) C- N E ) H-I

Answer 1

Cl2,CCl4 are zero dipole moment

NaBr has largest dipole moment in the gas phage

B. NaBr >>>>answer

28.

The electronegative difference between two atoms are more . It is more polar bond

Bond    electroneggative difference

N- O                        3.5-3 = 0.5

C- F                        4-2.5    = 1.5

C-P                        2.5-2.19 = 0.31

C-N                         3-2.5   = 0.5

H-F                        4-2.1    = 1.9 is more polar bond

E. H-F >>>>answer
