Determine if it is polar or non-polar molecule:
C3H6O
C2H5OH
SiCl4
NH3
CO2
C3H8
H2O
N2
My ans are:
Polar
Polar
Polar
polar
Nonpolar
nonpolar
polar
Nonpolar
are my answers correct????
I can't tell the structure from C3H8O (the first one)but C3H7OH would be polar.
The others look ok to me except for SiCl4. It is non-polar.
Your answers are almost correct. Here are the correct determinations for each molecule:
C3H6O - Polar
C2H5OH - Polar
SiCl4 - Nonpolar
NH3 - Polar
CO2 - Nonpolar
C3H8 - Nonpolar
H2O - Polar
N2 - Nonpolar
So, your answers for C3H6O, C2H5OH, NH3, CO2, and H2O are correct, but your answers for SiCl4, C3H8, and N2 are incorrect. SiCl4 and C3H8 are nonpolar, while N2 is also nonpolar.
Your answers are partially correct. Here's the correct classification for each molecule:
C3H6O: This molecule is polar. To determine its polarity, you need to consider the electronegativity difference between the atoms and the molecular shape. Carbon (C) and hydrogen (H) have similar electronegativities, so the C-H bonds are nonpolar. However, oxygen (O) is more electronegative than carbon, resulting in a polar C=O bond. Additionally, the geometry of the molecule, which is bent, leads to an overall polarity.
C2H5OH: This molecule is polar. Similar to C3H6O, the presence of an oxygen atom (O) that forms polar bonds with carbon (C) results in an overall polar molecule.
SiCl4: This molecule is nonpolar. Silicon (Si) and chlorine (Cl) have similar electronegativities, resulting in nonpolar bonds. Furthermore, the molecule has a symmetrical tetrahedral shape, which cancels out any potential polarity.
NH3: This molecule is polar. Nitrogen (N) is more electronegative than hydrogen (H), leading to polar bonds. Additionally, the triangular pyramidal shape of NH3 results in an overall polar molecule.
CO2: This molecule is nonpolar. Carbon (C) and oxygen (O) have similar electronegativities, resulting in nonpolar bonds. Also, the molecule has a linear structure with the oxygen atoms on opposite sides, canceling out any potential polarity.
C3H8: This molecule is nonpolar. Carbon (C) and hydrogen (H) have similar electronegativities, resulting in nonpolar bonds. Furthermore, the molecule has a symmetrical tetrahedral shape, canceling out any potential polarity.
H2O: This molecule is polar. Oxygen (O) is significantly more electronegative than hydrogen (H), leading to polar bonds. Moreover, the molecule's bent shape results in an overall polarity.
N2: This molecule is nonpolar. Nitrogen (N) and nitrogen (N) have similar electronegativities, resulting in nonpolar bonds. Additionally, the linear structure of the molecule cancels out any potential polarity.
Remember that determining molecular polarity involves considering the electronegativity difference between atoms and the molecular geometry or shape.
