For each compound below, identify any polar covalent bonds and indicate the direction of the dipole moment using the symbols 84 and δ-.

(a) hbr
(b) hci
(c) h2o
(d) ch40

H+   Br-

H+   Cl-

O₋₋ 2H++

CH3 O-   H+

Explanation:

Dipole moment occurs when there is bonding between a very strong electronegative element and hydrogen atom.

Electronegative elements are the element which attract electrons towards themselves, (that is they have strong affinity for electrons).

Generally, group 7 elements (Fluorine, Chlorine, Bromine, Iodine) of the periodic table are highly electronegative

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
