Question

Using the NAS idea, how many electrons are needed for the coumpoun HOCL?

Hint: remember H only need 2 electrons, rather than 8
a. 32
b. 18
c. 24
d. 14

Answer 1

The compound HOCl requires 14 electrons.

Step-by-step explanation:

To determine the number of electrons needed for the compound HOCl using the NAS (Noble Gas Electron Configuration) idea, we first calculate the number of valence electrons for each atom in the compound.

The valence electron count for H is 1, for O is 6, and for Cl is 7.

Next, we sum up the valence electron counts for each atom: 1 + 6 + 7 = 14.

Therefore, the compound HOCl requires 14 electrons.

Answer 2

The compound HOCl requires a total of 14 valence electrons. This includes 1 from hydrogen, 6 from oxygen, and 7 from chlorine, adding up to 14 valence electrons to satisfy the octet rule with the exception that hydrogen only needs 2 electrons. So the correct option is d.

Step-by-step explanation:

The compound in question is hypochlorous acid, which has the chemical formula HOCl. To calculate the number of valence electrons needed for this molecule, we consider the valence electrons of hydrogen (H), oxygen (O), and chlorine (Cl). Hydrogen needs 1, oxygen needs 6, and chlorine needs 7 valence electrons to complete its outer shell. Therefore, for one molecule of HOCl:

• Hydrogen (H): 1 × 1 = 1 valence electron
• Oxygen (O): 1 × 6 = 6 valence electrons
• Chlorine (Cl): 1 × 7 = 7 valence electrons

Adding these together, the total number of valence electrons needed for the molecule HOCl is 14 (1 + 6 + 7 = 14). Thus, the correct answer is (d) 14.
