Questions & Step-by-Step Solutions
Which of the following statements about haloalkanes is true?
Step 1: Understand what haloalkanes are. Haloalkanes are organic compounds that contain carbon, hydrogen, and at least one halogen atom (like chlorine, bromine, or iodine).
Step 2: Learn about electronegativity. Electronegativity is a measure of how strongly an atom attracts electrons. Halogens are more electronegative than carbon.
Step 3: Recognize the effect of electronegativity difference. Because halogens attract electrons more than carbon does, this creates a difference in charge within the molecule.
Step 4: Identify polarity. When there is a difference in charge distribution (due to electronegativity), the molecule becomes polar, meaning it has a positive end and a negative end.
Step 5: Conclude that haloalkanes are polar compounds because of the electronegativity difference between carbon and halogen.
