fill in the missing words\na) in an o-h bond a partial negative charge resides on the atom.\nb) in a c-o bond a partial negative charge resides on the atom.\nc) in an o-f bond a partial negative charge resides on the atom.\nd) in an h-br bond a partial negative charge resides on the atom.\ne) in a c-cl bond a partial negative charge resides on the atom.
Answer
Explanation:
Step1: Recall electronegativity concept
In a polar - covalent bond, the more electronegative atom attracts the shared electrons more strongly and has a partial negative charge.
Step2: Compare electronegativities for O - H
Oxygen is more electronegative than hydrogen. So in an O - H bond, the partial negative charge is on the oxygen atom.
Step3: Compare electronegativities for C - O
Oxygen is more electronegative than carbon. So in a C - O bond, the partial negative charge is on the oxygen atom.
Step4: Compare electronegativities for O - F
Fluorine is more electronegative than oxygen. So in an O - F bond, the partial negative charge is on the fluorine atom.
Step5: Compare electronegativities for H - Br
Bromine is more electronegative than hydrogen. So in an H - Br bond, the partial negative charge is on the bromine atom.
Step6: Compare electronegativities for C - Cl
Chlorine is more electronegative than carbon. So in a C - Cl bond, the partial negative charge is on the chlorine atom.
Answer:
a) oxygen b) oxygen c) fluorine d) bromine e) chlorine
