First let's remember how to draw lewis dot structure in generalIn the lewis dot structure model the points represent the valence electrons that each element has, these electrons are the ones that are shared to form a bond.For the element to be stable it must comply with the octet rule (each element must be surrounded by 8 electrons to be stable) But there are exceptions to this rule from elements that are stable with fewer electrons (Be, B, Al) and others that they can expand the layer and are stable with more than eight (S)In this case our compound () one of the elements that form it is B, which does not comply with the octet rule. electronic boron configurationBoron´s valence electrons: 3 Electronic configuration of fluorine. Fluorine´s valence electrons: 7its valence electrons are distributed to each atomBoron shares an electron with each fluorine so the fluorine can reach the octetSince boron is an exception, it is stable with 6 electrons

1) pentane is of higher Molecular mass than propane hence heavier member2) due to intermolecular hydrogen bonding methanol is liquid having lower molecular weight3) I) in methanol C = sp3ii) in methanoic acid C= sp25)I) i) The two carbon-oxygen bonds in the methanoate anion, HCO2-, have the same length due to resonance stabilization of the C-O bondExplanation:See attachment for question 4

Anonymous · Answer

1. There are stronger inter-molecular forces at play when a certain substance is a liquid as compared to a gas. Pentane is liquid due to the hydrogen bonding present between its molecules.2. Inter-molecular forces between propane molecules are weaker as compared to methanol. There are no hydrogen bonds present between the propane molecules.3. Methanol: Methanoic (formic) acid: 4. attached5. i) Since there are two resonance structures possible in this case, the bond length is given as an average value of the carbon-oxygen bond, one where it is a single bond and the other where its a double bond.ii) Continuing from the explanation above, the value of bond length in the case of methanoate anion would be in between the bond length of a single carbon-oxygen bond and a double carbon-oxygen bond in methanol.Hope that answers the questions, have a great day!

B, CExplanation:The atoms or ions with the valid Lewis dot structures are B and C.In A;The Lewis structure of the carbon is correct. Each of the four dots represent the four valence electrons.The  nitrogen with one dot on top, left and to the bottom and has a charge of minus 3 is wrong. For it to have a charge of -3 it must have 8 lewis dots ( two on the top, right, bottom and to the left) The nitrogen with four dots (on top, right, bottom and to the left) is wrong.In B;An oxygen has two dots on top and bottom and one dot to the left and to the right. This is correct , the 6 dots represent the valence electrons of oxygen.In C;A carbon has two dots on top, right, bottom and to the left and a charge of plus four. This is correct because the charge indicates that it has gained four extra electrons so its valence electrons is now 8.In D;An oxygen has two dots on top, left and to the bottom and a charge of minus 2. This is wrong because the lewis dots are incomplete. Two dots are missing.

Layne Mayer · Answer

Explanation:The lewis dot structure or electron dot structure is a notation that shows only the chemical symbol of the element surrounded by dots to represent the valence electrons. The chemical symbol represents the nucleus and all electrons except the valence electrons. The dots are arranged at the four sides of the symbol pairs called lone pairs. Those that are unpaired are called odd electrons. Learn more: Electron dot structure #learnwithBrainly

Na is in the first column on the periodic table so therefore it would have 1 valence electron D 1

Since carbon has 4 valence electrons, a total of 4 bonds will be drawn withing methane, one between each H and the center CHope this helps

Nash Gleason · Answer

You have to give all atoms their right charge

Anonymous · Answer

You use the element symbol and draw the valence electrons. The valence electrons is the number of electrons on the outer shell. An easy way to know how many valence electrons there are, you can look at a periodic table and see what group the element is in. Group 1 has 1 valance electron. Group 2 has 2 valence electrons, and so on... so in the example you gave me, since there is 3 fluorines, and 1 boron, you want to arrange the 3 fluorines around the 1 boron so the electrons can bond with each other.
