Answer:   A. alcohol

Explanation:  A Base is defines as the species which can accept positive species and donate its negative species.

It can also be defined as the species which can release hydroxide ions when dissolved in water. These are basically known as the Arrhenius bases.

Thus out of given options, alcohol (ROH) is the correct option which is not a base as it can donate its proton due to the fact that the hydrogen is attached to the electronegative atom oxygen making it a acidic proton.

Potassium hydroxide (KOH) and Sodium Hydroxide (NaOH) are basic in nature as these are the ionic species which releases hydroxide ions.

Romashka [77]

Answer: Option (2) is the correct answer.

Explanation:

Atomic number of oxygen atom is 8 and its electronic distribution is 2, 6. So, it contains only 2 orbitals which are closer to the nucleus of the atom.

As a result, the valence electrons are pulled closer by the nucleus of oxygen atom due to which there occurs a decrease in atomic size of the atom.

Whereas atomic number of sulfur is 16 and its electronic distribution is 2, 8, 6. As there are more number of orbitals present in a sulfur atom so, the valence electrons are away from the nucleus of the atom.

Hence, there is less force of attraction between nucleus of sulfur atom and its valence electrons due to which size of sulfur atom is larger than the size of oxygen atom.

Thus, we can conclude that the oxygen atom is smaller than the sulfur atom because the outer orbitals of oxygen are located closer to the nucleus than those of sulfur.

arsen [322]

6 is the fourth significant figures

if the number behind it is 5 or more then 5, you must add 1 to the number and ALL the number behind it will turn into 0

so that the answer is 42560
