Which molecule is a stereoisomer of trans-2-butene?
Elina [12.6K]

Answer:

D

Explanation:

Stereoisomers are molecules that have the same molecular formula but different 3-d arrangement of atoms. Three types exist but we are focusing on geometrical cis-trans isomerism here. In a single bond, the molecules can rotate around fixed points and there is no fixed 3-d geometry. In butene and other double-bond-containing molecules (the double bond is signified through the "-ene" suffix and the "-2-" indicates that the double bond begins on the second carbon in the chain), rotational motion is stopped by the double bond. This causes two different types of molecules to occur in nature: cis-2-butene, in which the carbon atom in the chain is on the same side at both ends of the double bond, and trans-2-butene, in which the carbon atom is on opposite sides (like a beach chair if the seat was a double bond). So the stereoisomer of trans-2-butene is cis-2-butene, which is Option D.

Using the periodic table determine the number of neutrons in O that has an atomic mass of 16
Soloha48 [4]
You will find that the atomic weight of oxygen is about 16. Since the weight of the protons and neutrons is about 1 (the electrons weigh almost nothing compared to protons and neutrons) and we know we have 8 protons in the nucleus, we can calculate the number of neutrons by subtracting 8 from 16 (16 - 8) which equals 8.

. Using the following equation: F = ma Solve for m (1 point)
Oksanka [162]
<span>To solve for m in the equation F = ma, you must divide both side of the equation by a. This will make the equation look like F/a = ma/a. Since m is being multiplied by a, dividing it will cancel out. Now making the final equation look like F/a=m and/or m=F/a.</span>

Which element in period 4 has the highest electronegativity?
sashaice [31]
It will be K-potassium because when you go down a group the electronegativty gets bigger while when you go across the period they get smaller because of the valence electrons. Group 8 has the lowest electronegativty because they have a full outer shell. From left to right on the periodic table it decreases but from top to bottom it increases.
