The s orbital is the closest orbital to the atom and contains the leasy number of electrons. Did i help?
Answer:
AlF₃ is Lewis Acid
CH₃F is Lewis Base
Explanation:
According to Lewis concept ,"those compounds which donate pair of electrons are called as Lewis Base and those accepting pair of electrons are called as Lewis Acid.
In Given Reaction,
<span> AlF</span>₃<span> + CH</span>₃<span>F → CH</span>₃⁺<span> + [AlF</span>₄<span>]</span>⁻
AlF₃ is acting as acid because the octet of Al is not complete, hence it has tendency to accept electrons.
CH₃F is acting as a base because the F atom containing three lone pair of electrons can donate it to Al metal resulting in the formation of electrophile i.e. CH₃⁺.
11. <span>Ionic compounds that dissolve in water conduct electricity because they break into ions that move freely.
12. </span><span>Solid metals are good conductors of heat and electricity.
13. </span>Molecular compounds that dissolve in water do not conduct electricity because no charged particles are present.
14. <span>Because the electrons in a molecule of hydrogen fluoride (HF) are more strongly pulled toward the fluorine atom, the molecule is polar.
</span>
15. A metal crystal consists of positively charged metal ions embedded in a "sea" of freely moving valence electrons.
16. <span>The properties of solid metals can be explained by the structure of and the bonding among the metal atoms. = True
17. </span><span>Orderly crystal shapes, high melting points, and electrical conductivity, when dissolved in water, are properties of ionic compounds. = True
18. </span><span>When electrons are transferred between two atoms, a covalent bond is formed. = False (</span><span>When electrons are shared between two atoms, a covalent bond is formed.)
19. </span><span>A low melting point is one property of molecular compounds. = True
20. </span><span>A nonpolar bond is formed when two atoms share electrons unequally. = False (</span><span>a polar bond is formed)</span>
Meiosis 1 makes 2 Haploid cells from one Diploid cell. Meiosis 2 separates the sister chromatids in the haploid cell in order to make 4 daughter cells.
