What is reflection symmetry in chemistry?
In a rotation, the line of points that stay in the same place constitute a symmetry axis; in a reflection the points that remain unchanged make up a plane of symmetry. The symmetry elements that a molecule (and any other 3-D object) may possess are discussed below.
Is symmetry the same as reflection?
Reflection symmetry is also known as line symmetry or mirror symmetry. It states that if there exists at least one line that divides a figure into two halves such that one-half is the mirror image of the other half….Is Parallelogram Symmetrical?

What is the equivalent resistance?
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. Essentially, the circuit is designed either in Series or Parallel. Electrical resistance shows how much energy one needs when you move the charges/current through your devices.
How are a line of reflection and a line of symmetry related?
We say there is symmetry when the exact reflection or mirror image of a line, shape or object gets created. The line of symmetry can be defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves.
What is C2 axis symmetry?
A C2 axis of symmetry means that I should be able to rotate the molecule about an axis by 180∘. But I would need a composition of the following two rotations. 90∘ rotation about C=C=C axis. 180∘ about the perpendicular bisector of C=C=C.
How do you find the equivalent resistance between two points?
The two resistances R1 and R2 of 4 ohms are in series therefore their equivalent resistance,
- R’ = 4 Ω + 4 Ω = 8 Ω
- Now the resistances R’, R3 and R4 are in parallel so the equivalent resistance of the circuit would be.
- Therefore the equivalent resistance between the two points A and B in the given circuit is 1.85 Ω.
What are symmetry equivalents?
Symmetry equivalent positions are shown relative to this initial point. The second symbol represents a point related by symmetry to the initial point, but now at a height 1/2+ z .
How many reflections does an asymmetric shape have?
The number of reflections depends on 2 factors: The resolution and the volume of the asymmetric unit. In point group 6 , there are 6 a.u.s; in 622, there 12; in 222 there are 4 if the space group is primtivie or 8 if it is centred (C/F/I).
What are the lines of symmetry of a shape?
• If a shape can be folded in half so that one half fits exactly on top of the other, than we say that the shape has got line symmetry. • The fold is called a line of symmetry, it divides the shape into two equal parts! • The lines of symmetry may be vertical, horizontal or diagonal
What is the symmetry equivalent of a general reflection with HKL?
Applying these to a general reflection with indices hkl gives the following symmetry equivalent reflections hkl, – hk – l, – h – k – l , h – kl, respectively.
