Answer:
CCl4 - Nonpolar
CH3OH - polar
NH3 - polar
CS2 - Nonpolar
Explanation:
One important thing that we should know is that polarity has to do with the presence of a resultant dipole moment in a molecule.
Dipole moment is a vector quantity, This means that its direction is also taken into account when discussing the dipole moment of molecules.
Hence, symmetrical molecules such as CS2 and CCl4 are non-polar even though they have polar bonds because their dipoles cancel out(zero resultant dipole moment).
On the other hand, NH3 and CH3OH are non-symmetrical molecules hence they possess an overall dipole moment and are polar molecules.
Tell the teacher, do NOT clean it up yourself.
Answer:
Option B
Explanation:
Energy required to remove outermost electron from an neutral atom is called ionization energy or first ionization energy (
)
Energy required to remove an electron from M+ ion is called second ionization energy (
).
Energy required to remove an electron from M2+ ion is called third ionization energy ).
Therefore, among the given options:
Therefore, the correct option is b
Different species have different names that start with different letters. However, all species names are generally preceded by a genus name
