The polarity of a specific alcohol can depend on the length of the carbon and hydrogen chains formed, such that an alcohol with a very long chain can exhibit more nonpolar characteristics. The alcohol or hydroxyl (-OH) group can have compounds that are very polar like methanol and ethanol, while another like hexanol is more nonpolar than polar.Know More
This is because the chain length increases when comparing methanol and hexanol. However, there is still a small polar effect evident in hexanol. Methanol and ethanol are soluble in water.
To find if an alcohol is polar or tends to be nonpolar, students can use the rule that if the ratio between carbon and oxygen in the compound is less than 4:1, then the alcohol compound is miscible in water and so it is polar.Learn more about Atoms & Molecules
Water is a polar molecule, and polarity occurs when the electrons in molecules are not spread evenly. This causes on end of the molecule to be negative, while the other is positive.Full Answer >
COCl2 is a polar molecule because the dipole between the carbon and the chlorine atoms is not equal to the dipole between the carbon and oxygen atoms. Molecules are only non-polar if they contain no polar bonds or if the partial charges cancel out each other.Full Answer >
Due to the presence of an oxygen molecule, the chemical compound fluorenone is more polar than fluorene. The difference in electronegativity between the bonded carbon and oxygen present in fluorenone creates a dipole that increases fluorenone's polarity.Full Answer >
Carbon dioxide, or CO2, is a nonpolar molecule. The molecule has a linear geometry due to the molecular arrangement of the compound. It is arranged with a central carbon molecule and two oxygen atoms surrounding the carbon atom.Full Answer >
