What is the angle between the carbon-oxygen bond and one of the carbon-fluorine bonds in the carbonyl fluoride ( cof2 ) molecule
?
2 answers:
Answer: More than .
Explanation:
In carbonyl fluoride molecule, carbon is hybridized with planar geometry. Oxygen in doubled bonded to the carbon and two fluorine atoms are single bonded with carbon atom.
In hybridization the angle between the two adjacent hybridized molecular orbitals is at
.Since, lone pair present on the oxygen atoms will repel the carbon-fluorine bond pairs away by which angle between (O-C-F) will become more than

<u>Answer:</u> The theoretical yield of iron (II) oxide is 5.53g and percent yield of the reaction is 93.49 %
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
....(1)
- <u>For Iron:</u>
Given mass of iron = 4.31 g
Molar mass of iron = 53.85 g/mol
Putting values in above equation, we get:
For the given chemical reaction:
By Stoichiometry of the reaction:
2 moles of iron produces 2 moles of iron (ii) oxide.
So, 0.0771 moles of iron will produce = of iron (ii) oxide
Now, calculating the theoretical yield of iron (ii) oxide using equation 1, we get:
Moles of of iron (II) oxide = 0.0771 moles
Molar mass of iron (II) oxide = 71.844 g/mol
Putting values in equation 1, we get:
To calculate the percentage yield of iron (ii) oxide, we use the equation:
Experimental yield of iron (ii) oxide = 5.17 g
Theoretical yield of iron (ii) oxide = 5.53 g
Putting values in above equation, we get:
Hence, the theoretical yield of iron (II) oxide is 5.53g and percent yield of the reaction is 93.49 %
