Can you explain this answer? defined & explained in the simplest way possible. The atoms have been given different labels to allow us to follow their transformations.Here you can find the meaning of Which of the following letters have reflection line of symmetry about vertical mirror?a)Cb)Bc)Vd)QCorrect answer is option 'C'. We can define the x-axis to run through the carbon-carbon double bond while the y-axis bisects this bond at right angles. The planar molecule ethene provides a simple example to demonstrate the effects of the symmetry elements described above. Molecular symmetryĭetermining the symmetry elements present in a molecule involves considering which rotations, reflections and inversions will leave the shape of the molecule unchanged even though individual atoms will have moved, the final result must be indistinguishable from the starting structure. The inversion symmetry element is denoted by the symbol i. In this case this is the same as a 180° rotation, but generally these two operations may give different results. This means that our original point moves from (1,2) to (–1,–2). The inversion operation simply reverses the sign on all the coordinates. We could clearly rotate a point through any angle, but the transformation of the coordinates will be harder to describe. Thus, the absolute value of both 2 and –2 is 2. Note that where the absolute value of a number is referred to, this is simply its magnitude without taking account of whether it is positive or negative. If we can understand the behaviour of individual points when symmetry operations are applied, and identify appropriate symmetry elements (mirror planes, rotational axes and inversion centres), then we will be able to combine several points and study molecules. We saw in a previous article 6 that the position of any point (and consequently any atom) can be defined in terms of its x and y coordinates, denoted as ( x, y). 4 Ji-Won Son from the State University of New York in Buffalo, US, has also suggested that there is confusion between reflection and rotation among both students and pre-service teachers. Which of the following letters have reflection line of symmetry about vertical mirrora)Cb)Bc)Vd)QCorrect answer is option C. This indicates that this is a vertical (up/down) reflection or a reflection over the (x)axis. (y)coordinates all become the opposite integers of the original (y)coordinates. Xenia Xistouri and Demetra Pitta-Pantazi from the University of Cyprus have suggested students’ mathematical performance in reflective symmetry tasks can be predicted by their general mathematical achievement, perspective taking abilities and spatial rotation abilities, in descending order of importance. In a reflection, the figure flips across a line to make a mirror image of itself. However, more homemade teaching aids can be just as effective, for example: a collection of objects showing different symmetry a magnet-backed mirror and a set of modified molecular models and a frame to demonstrate different symmetry axes. 1 Recent advances in 3D printing provide interesting opportunities in this area. Teaching aidsĮxtending these principles to three dimensions is much easier using molecular models, and hand-held models probably have an advantage over computer generated ones. The way that simple symmetry elements apply to molecular structures can be introduced by working in two dimensions and considering planar molecules. The concept of symmetry is introduced in GCSE mathematics, but provides an incredibly powerful tool for understanding molecular behaviour in topics such as spectroscopy and quantum mechanics.
