SiCl4 is non-polar.

To determine if a molecule is polar or non-polar, you need to consider its molecular geometry and the polarity of its individual bonds.

- C3H6O (acetone) is a polar molecule because it contains a polar C=O bond. Additionally, the molecular geometry of acetone includes a slightly electronegative oxygen atom, causing the overall molecule to have a dipole moment.

- C2H5OH (ethanol) is also a polar molecule due to the presence of a polar C-O bond and a polar O-H bond. These polar bonds and the molecular geometry result in a net dipole moment.

- SiCl4 (silicon tetrachloride) is a non-polar molecule because it has a tetrahedral arrangement with the four chlorine atoms symmetrically arranged around the central silicon atom, resulting in a net dipole moment of zero.

- NH3 (ammonia) is a polar molecule. It has a trigonal pyramidal molecular geometry, with the three hydrogen atoms and lone pair of electrons creating an imbalance in electronegativity, resulting in a net dipole moment.

- CO2 (carbon dioxide) is a non-polar molecule. While it has two polar C=O bonds, the molecule's linear geometry results in the individual bond dipoles canceling each other out, giving a net dipole moment of zero.

- C3H8 (propane) is a non-polar molecule. It consists of carbon and hydrogen atoms bonded in a tetrahedral arrangement, resulting in a symmetric distribution of polarity and a net dipole moment of zero.

- H2O (water) is a polar molecule. It has a bent molecular geometry, with two hydrogen atoms and two lone pairs of electrons around the central oxygen atom, creating an uneven distribution of charge and a net dipole moment.

- N2 (nitrogen gas) is a non-polar molecule. It consists of two nitrogen atoms sharing a triple bond and has a linear molecular geometry, resulting in a symmetric distribution of charge and a net dipole moment of zero.

Based on these explanations, your answers are as follows:
C3H6O (acetone) - Polar
C2H5OH (ethanol) - Polar
SiCl4 (silicon tetrachloride) - Non-polar
NH3 (ammonia) - Polar
CO2 (carbon dioxide) - Non-polar
C3H8 (propane) - Non-polar
H2O (water) - Polar
N2 (nitrogen gas) - Non-polar
