Work Step by Step
a. ${}^{8+}H-F^{\delta -}$ - This is correct. The hydrogen atom has a partial positive charge ($\delta^+$) and the fluorine atom has a partial negative charge ($\delta^-$), indicating a polar bond.
d. ${}^{\delta +}Br-Br^{\delta -}$ - This is incorrect. The bond between two bromine atoms is non-polar, as both atoms have the same electronegativity and share the electrons equally. The correct bond polarity should be ${}^{\delta +}Br-Br^{\delta +}$.
b. ${}^{8+}Cl-I^{\delta -}$ - This is correct. The chlorine atom has a partial positive charge ($\delta^+$) and the iodine atom has a partial negative charge ($\delta^-$), indicating a polar bond.
e. ${}^{8+}O-p^{\delta -}$ - This is incorrect. The bond between oxygen and phosphorus is polar, with the oxygen atom having a partial negative charge ($\delta^-$) and the phosphorus atom having a partial positive charge ($\delta^+$). The correct bond polarity should be ${}^{\delta -}O-P^{\delta +}$.
c. ${}^{8+}Si-S^{\delta -}$ - This is correct. The silicon atom has a partial positive charge ($\delta^+$) and the sulfur atom has a partial negative charge ($\delta^-$), indicating a polar bond.
