    Explanation: You have to consider three things. 1. First, are the bonds polar? Look at differences in electronegativity and if it is >0.5, bonds are polar. 2. Second, does the molecule have unshared electron pairs? If so, they generally lead to a polar molecule. 3. Third, is the molecule symmetriRead more

    Explanation:

    You have to consider three things.

    1. First, are the bonds polar?

    Look at differences in electronegativity and if it is >0.5, bonds are polar.

    2. Second, does the molecule have unshared electron pairs?

    If so, they generally lead to a polar molecule.

    3. Third, is the molecule symmetric?

    If so, then although the bonds may be polar, the symmetry cancels out the individual bond polarity and the molecule is non polar.

    CF4 follows all the rules above and has a symmetric distribution of charge, making it nonpolar. The others all have asymmetric charge distributions.

    Hence, CF4 represents a Non-polar molecule.

    Explanation: The atomic number of : Phosphorus = 15 Aluminium = 13 Chlorine = 17 Magnesium = 12. Hence atomic number of Chlorine is more than that of Phosphorus.

    Explanation:

    The atomic number of :

    Phosphorus = 15

    Aluminium = 13

    Chlorine = 17

    Magnesium = 12.

    Hence atomic number of Chlorine is more than that of Phosphorus.

    Explanation:

    Browning of paper in old books are caused by Oxidation of Celluose.

    Paper is mainly made up of white cellulose but it also contains lignin present in the wood which when exposed to the air and sunlight turns the paper Yellowish/Brownish.

    Lignin is a polymer which makes the wood of the trees stiff to make trees stand upright as well as it also protects it from pests and other damage.
