Answer:
Pi bond
Explanation:
Pi bond is the type of covalent bond which results from formation of molecular orbital by the side-to-side overlap of the atomic orbitals along the plane perpendicular to the line which connects nuclei of the two atoms in which the bond is formed. It is denoted by symbol π.
The bond is not symmetrical to the internuclear axis and on rotation the axis, the bond breaks.
Answer:
1,1-, (Z)-1,2-, and (E)-1,2-dibromoethene
Explanation:
Their structures are shown below.
The 1,2-dibromoethenes (2 and 3) are positional isomers
of 1,1-dibromoethene (1).
(Z)-1,2-dibromoethene (2) and (E)-1,2-dibromoethene (3) are stereoisomers (geometric isomers) of each other.
Answer:
0.112 M.
Explanation:
- Molarity is the no. of moles of solute in a 1.0 L of the solution.
M = n/V.
<em>M = (mass/molar mass)solute x (1000/V of the solution).</em>
mass = 127.62 g.
molar mass = 286.138 g/mol.
V of the solution = 4.0 L = 4000.0 mL.
<em>∴ M = (mass/molar mass)solute x (1000/V of the solution)</em> = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = <em>0.1115 M ≅ 0.112 M.</em>
