WebStep 1: Give each atom connected to the chiral center a priority based on its atomic number. The higher the atomic number, the higher the priority. So, based on this, bromine gets priority one, the oxygen gets priority two, the methyl carbon is the third and the hydrogen is the lowest priority-four: Step 2: Web9. I am trying to figure out the configuration for this chiral carbon to answer a homework question, however they arbitrarily include a "D" group as shown in the image. My guess is that it is some higher priority group than the carbon, and lower priority than the halide, making the configuration (S). Is this correct? cuban dolly

WebMeso Compound is Optically Active. A non-optically active member of a collection of stereoisomers, of which at least two are optically active, is known as a meso compound or meso isomer. This means that despite having two or more stereogenic centres, the molecule is not chiral. They’re achiral compounds, meaning they feature several chiral ... WebThe ability of a solution to rotate plane-polarized light in this fashion is called optical activity, and solutions which have this ability are said to be optically active. Figure %: Rotation of plane-polarized light by optically active compounds. Using a technique called polarimetry, optical activity is measured by a device called a polarimeter.
